A website contact form mails the site's own address: From and To are
both info@thesite, and the person who filled the form in is in Reply-To.
Replying addressed the draft to info@thesite -- the site's own desk --
instead of to them.
The reply already knows two shapes. A message somebody sent me is
answered to its Reply-To, which is what that header is for. A message
*I* sent is answered to the people I wrote to, and deliberately not to
my own Reply-To, which is where answers to me belong and would send my
reply to myself. A contact form passes the test for the second: every
address in From is mine.
So it fell down the chain the second shape keeps for a message with
nobody obvious to answer -- To without me, then Cc, then, having run
out, every address on the message, which here was mine alone.
The Reply-To now goes in that chain, one step before the last: when no
recipient but me is left and the message names a Reply-To that is not
mine either, that address is who it is really from. Keeping it after the
Cc is what leaves a message I did send alone -- somebody I actually
wrote to still beats my own Reply-To, which is the case the existing
guard was built for and its test still holds.
No new strings.
Reading a message fetches its remote images through this server, so the
sender learns nothing about the reader. Quoting the same message into a
reply fetched them directly: same pixel, same reader, but the request
carried their IP and user agent -- exactly what the proxy withholds.
A quote now proxies them the way the message view does. That alone would
be wrong, because a proxied URL belongs to this deployment: sent
unchanged it would reach the recipient as images only this server can
serve, broken for them and a beacon back here. So buildEmailObject turns
them back into the addresses they came from, beside the pass that
restores images blocked under pr411 and the one that turns editor blob
URLs into cid: references.
Deployments with the proxy off are unaffected: the quote fetches
directly, as reading does there.
Three tests from pr411 asserted the address sat in src when images were
allowed, which was the old behaviour; they now ask whether the draft
fetches it at all, proxied or not.
No new strings.
Replying sanitized the quoted body with allowRemote: true, so quoting
fetched every remote image in the message whatever the reader had
decided about it. A tracking pixel in the quote then reported the
message read, and the address live, to whoever was counting -- the thing
leaving the images blocked was meant to prevent. Edit as new and opening
a draft that quotes a message did the same.
The decision now lives in one place, remoteImagesAllowed(), asked with
the same inputs the reader's answer used: the image policy, the trusted
senders, whether the sender is a contact, and whether Show images was
pressed on that message. The last of those was component state, so it
moves to the mail store, where the composer can see it.
Blocked images already keep their address in data-ihm-remote, so nothing
is lost by not fetching: it goes back on the way out, and the sent quote
is what its sender wrote. The recipient's client decides for itself, as
it would with any other client's reply.
Before pr408 this needed a rich-text default to reach; the format offer
made it reachable from plain text, which is how it was found.
No new strings.
Switching a reply between plain text and rich text converted whatever
body the draft was showing. Going from plain text to rich, that meant
the quoted message came back as the "> " text quote run through a
converter -- the sender's formatting, images and links gone, even though
the original markup was sitting on the draft untouched.
Both forms of the quote are prepared when the reply opens, so keep them
on the draft and re-attach the right one when the format changes. Only
what the author typed above the quote is converted. Where the quote
can't be found any more -- edited by hand, or a draft that quotes
nothing -- the whole body is converted as before, which is what every
non-reply draft does.
No new strings.
A reply opened in the format the settings ask for, whatever the message
being answered was written in, and the per-draft switch was buried in
the composer's ⋮ menu. Replying in plain text to a rich text message
throws away the formatting; replying in rich text to a plain-text one
overrides what the sender chose to write in.
When the two disagree the composer now says so above the editor -- "This
message is rich text", with a Switch button and a dismiss -- and the
draft still opens in the format the settings ask for. Switching converts
that draft only and leaves the setting alone; switching from the ⋮ menu
answers the offer too. Forwards get it as well, where the formatting
being passed on is somebody else's.
What counts as rich text is hasHtmlAlternative(), which reads the body
part's own type: `htmlBody` is derived (RFC 8621 4.1.4), so a plain-text
message has one too and its presence proves nothing.
The mock said otherwise -- it returned an empty `htmlBody` for a
plain-text message, where Stalwart 0.16.21 returns the text/plain part
in both lists. Both builders now answer as the server does, so the path
this feature depends on is exercised in development rather than only
against a real mailbox.
Two new strings, translated in all nine catalogs; the buttons reuse the
menu's existing "Switch to plain text" / "Switch to rich text". The
count falling back to English stays at 16 in every language.
Fixes#407
Settings > General > Composing has a new switch, "Open the composer full
screen". With it on, every new composer, whether a new message, reply,
forward or reopened draft, starts maximized. Restore still shrinks it to
a window. A draft put back after an undone or failed send keeps the size
it had. It's off by default, and on a phone, where the composer already
fills the screen, it changes nothing.
One new string, translated in all nine catalogs. The count falling back
to English stays at 16 in every language.
Fixes#401
Ask for the account password before minting an app password, and keep
sessions the proxy checks from writing the account's own registry objects,
so a session left open on someone else's machine cannot take a credential
away from it. The password is compared with what the session holds; Stalwart
is asked only when 2FA moved the session onto an app password.
Serve attachments and proxied images with no-store on a device that is not
the person's own. Give files from a winmail.dat only the types the server
would show inline. Strip direction controls from sender and attachment
names and from saved filenames.
On signing out, send what is inside its undo window, then close every
composer, so the next person to sign in does not find the last one's draft.
Group sessions by the account Stalwart names and its server, so "sign out
other sessions" also reaches a session opened as a bare or differently
cased username.
Rewrite mail CSS in place instead of cutting pieces out, so a strip can no
longer join text into a closing </style>, and escape < last. Decode escaped
letters before checking, parse url() properly and drop CSS that cannot be
parsed, and disable @import and image-set() in every spelling. The body
element's style goes through the same path.
Give <area> links the same target, rel and click handling as <a>, strip
<style> blocks from HTML quoted into the composer, and contain the editor's
layout as .message-body already is.
Takes the flat module count from 66 to 42, continuing what admin/ and
calendar/ started.
lib/mailbox/ archiveDate, emptyFolder, folderMove, labelTree,
mailboxName, mailboxRoute
lib/sieve/ sieve, sieveApply, sieveFolders
lib/input/ keyboard, swipe, touch, listSelection, dropUpload
lib/notify/ notify, webpush, webpushEnable
lib/sw/ swCache, swFacts, staleBuild
lib/text/ html, markdown, text, emlName
FOUR THINGS THE FILENAMES GET WRONG, each checked by reading the file
rather than trusting what it is called:
- appFolder is not a mailbox. It is the `ihasmail` folder in JMAP
*Files*, where the client keeps signature images and synced settings.
It stays flat.
- format holds no formatting of text. It re-exports the date and clock
formatters, so it belongs with dates/datetime, not with text/.
- preview is the file viewer deciding what it can show without
downloading, and source is where to point someone asking for this
instance's AGPL source. Neither is about text.
- notify is not Web Push. It is the tab title, the favicon badge and
the new-mail sound -- in-app notification, which is why it sits with
webpush rather than under sw/ with the service worker's own concerns.
threadScroll stays flat too: it decides where a conversation opens, which
is view state rather than a gesture, and input/ is honest only if
everything in it interprets something the reader did.
No behavior change. Almost every reference was on the @/ alias; eight
relative imports in files that did not move, or that moved away from a
sibling, needed rewriting by hand.
ihasmail could hand a file to the share sheet as of #306, and was still
not in it. Share a photo from the gallery, a link from the browser or a
document from a file manager and ihasmail was not among the places it
could go, which is the one piece of operating-system integration a mail
app is expected to have.
A share is a POST that navigates, and there is nothing on this side that
can answer one: the app is a client-side router with no endpoint at that
address, and the server behind it would need a route that understood the
composer. So the service worker intercepts it, takes the form body, puts
the files and text in its cache, and redirects to the app -- which finds
them on start and opens a draft holding them. The subject is the shared
title, the text and the link become the body, and files are attached and
begin uploading. Nothing is addressed: a share says what to send, never
who to.
The body is pushed in above the signature rather than passed to open(),
because open() only fits a signature when it is given no body at all --
the obvious version drops the signature from every message that started
as a share, and nothing about the draft looks wrong afterwards.
Collected on every start rather than when the launch URL says so. A share
to a signed-out ihasmail lands on the sign-in page, and there is no
account to attach to until it is done, so the payload has to outlive a
redirect and a login -- which the query string does not. What that costs
is a stash nobody came back for, so it carries a timestamp and expires
after ten minutes.
`accept` names wildcard families and explicit types and extensions both.
A mail client attaches anything, but wildcards are not in the
specification and operating systems differ over which form they match on,
so the explicit list is what holds if the families are ignored.
The cache name the worker and the app have to agree on now has one home
on the app side. It was written out twice, and a drift would not fail --
a push verification would simply never complete and a share would arrive
at an empty composer.
One case is deliberately left to fail loudly: an app still installed
whose worker has been cleared away POSTs to the server, which answers
405. A server route would trade a plain error for a silent nothing, and
the payload is gone in both -- it only ever existed in that request body.
Verified by test, not on a device: Android is the only place this exists
at all, and the extension driving Chrome is not connected here. The
handoff is pinned from the tab's side against a cache shaped exactly as
the worker leaves it, since the two files never see each other.
Replying to a thread whose last message I sent addressed the reply to me:
Reply put my own address in To, and Reply all put me in To with everyone
I had actually written to demoted to Cc. Following up on your own last
message is an ordinary thing to do, and this made it useless.
There was already a guard for exactly this, and the guard was sound. What
it rested on was not. It asked whether an address was in the identity
list, and that question has a wrong answer in more situations than it has
a right one:
- the list is empty until identities load;
- an alias or a shared mailbox is not in it at all;
- it compared lowercased strings with `includes` where the rest of the
codebase uses `sameAddress`, so an identity address stored with
whitespace was enough to break it;
- the check ran on the address the reply was about to go to rather than
on the sender, so a message of mine carrying a Reply-To skipped it
entirely and my reply went to my own desk;
- and the Reply all branch never filtered my own address out of To, though
the Reply branch did.
Every one of those failed silently, which is why five of them accumulated.
So the folder is asked first: a message in Sent is mine whatever address
it went out as, and `mailboxIds` is already fetched in LIST_PROPS with
roleId("sent") on the mail store, so this costs no request. The identity
list stays as a second opinion, now compared with `sameAddress`, and the
whole test keys off the sender rather than off the computed recipient.
Two cases remain unanswerable and are commented rather than papered over:
a message from an unlisted alias that is not in Sent either, and any
message at all when identities failed to load and it is not in Sent.
Neither signal exists. Both are far narrower than what was broken.
Reply addressing had no tests at all, which is how a guard this
load-bearing came to be wrong five ways at once. Fifteen now, seven of
which fail against the old code.
A sweep of lib/ and store/ for user-facing English, after the views were done.
The pattern here is the one #248 found: a module returns an English sentence
and the view renders it without asking for a translation.
Scheduled send was entirely untranslated. The four presets -- Later today,
Tomorrow morning, Tomorrow afternoon, Monday morning -- were rendered raw, and
scheduleError() returned three English sentences straight to the picker.
describeSpan() built "30 days" by appending an "s" unless the count was one,
which is English grammar written into the code: it produces the right German
only by the two languages happening to agree, and Russian needs three forms.
It is plural() now. scheduleError translates in place rather than returning a
key, because it composes a sentence around that span.
Read receipts: refusalText() returns five explanations, all rendered raw in
MessageView, and the offered case was a template literal -- "Requested, to
x@y. Never sent automatically." -- with the address concatenated in. It takes
a placeholder now, so the sentence can be reordered.
Compose: the sending toast and its Undo, the Open draft action, the two
attachment failures, and three thrown errors that surface to the reader as
toasts.
Two swipe labels, Add star and Remove star, are rendered through
t(desc.label) and have never been in any catalogue -- the coverage scan that
found the other 176 only looked at t("literal") sites, so labels reaching t()
through a variable were invisible to it. Every such table is now enumerated
and all 61 values checked: these two were the only ones missing.
17 strings and 3 plural forms are new and land with each language.
Verified: typecheck clean, 1000 tests pass.
FEATURES has always said attach-from-Files works "however large", because a
blob the account already holds is attached by reference and nothing is
sent. The code checked every file against maxSizeUpload regardless, so the
two disagreed and the code was the one that was wrong.
maxSizeUpload is what the server will accept for a single upload (RFC
8620). It bears on a file that is about to be uploaded and on nothing
else. Applying it to a by-reference attachment refused a 60 MB message the
server was already storing, on the grounds that it could not have been
uploaded -- which it was not being. Forwarding a large message as an
attachment hit exactly that.
A file from somebody else's account is fetched and re-uploaded into this
one, because a message can only carry blobs from the account sending it.
That upload is real and the limit is real for it, so it still applies
there.
`BASE_PATH=/mail` mounts the whole app under a prefix, for a host that is not
ihasmail's alone. Unset -- every deployment that exists -- is the domain root
and is byte-for-byte what it was: the canonical form of the setting is the
empty string, and `""` concatenated onto `/api/health` is `/api/health`.
That choice of canonical form is the whole design. A trailing slash would have
been the obvious alternative, and it fails quietly in exactly one place: at the
root it makes `//api/health`, which is not a path on this host but a
protocol-relative URL to a host called `api`. One call site forgetting to
branch is a request leaving the origin. So the empty string, one leading slash,
no trailing one, worked out once in `scripts/basePath.mjs` -- plain JS, next to
`version.mjs`, because the web build and the server both have to reach the same
answer and two implementations of "what does /mail/ mean" is precisely the bug
where the server serves an app whose script tags point somewhere else.
`/mail`, `mail`, `/mail/` and `//mail//` all mean the same mount; a deployment
should not fail over a trailing slash.
Unlike everything else ihasmail is told, this one cannot wait for the process
to start. The bundle writes its own asset URLs into index.html, so `BASE_PATH`
is read at build time for Vite's `base` as well as at run time for the routes,
and the Dockerfile carries one value into both. Get them out of step and the
page comes up blank with a 404 in a console nobody has open -- so the static
handler, which is reading index.html anyway, checks what it asks for and says
so in the log once per build.
Everything moves together. The API mounts at `${base}/api`; the router is
given the base once, so every `<Route path>` and `<Link href>` stays written
root-absolute and wouter does the rest; `apiFetch` adds the prefix in one place
rather than at forty call sites; the session cookie's Path narrows to the mount
so two instances on one host cannot sign each other out.
Two things need no prefix at all, and it is worth saying why they were not
given one. A manifest's members resolve against the manifest's own address, so
relative URLs there follow the mount with nothing substituted at build time --
which is also why `public/` needed no template step. The service worker is the
same trick: it is served from the mount, so `new URL("./", self.location)`
tells it where that is, and a worker that derives the value cannot disagree
with the page that registered it.
Anything outside the mount is a 404 rather than the app shell, and
`stripBasePath` does not use `startsWith` -- under `/mail` this process shares
a hostname, and answering `/mailbox` with our index would shadow a neighbour
instead of letting it 404 honestly. For the same reason the notification-click
handler now checks the path as well as the origin: `includeUncontrolled` widens
`matchAll` to the whole origin, which off the root would have navigated a
stranger's tab to our inbox.
Inline images in a draft were the one silent trap. They are matched by their
blob URL on the way out, once unanchored and once anchored, and a bare
`/api/blob/` still appears inside `/mail/api/blob/...` -- so one pattern would
have replaced the tail and left `/mail` in front of a `cid:`, and the other
would have missed and sent the message linking to the sender's own webmail.
Both patterns are built from the base now.
Forwarding quoted the original into a new message, which is the right
thing for passing on something to be read and the wrong thing for passing
on something to be looked at. Quoting rewrites the body, drops the
headers, and re-parents the attachments, so a bounce, a phishing report or
anything else where the message itself is the evidence arrived altered.
Forward as attachment sends the message whole, as a message/rfc822 part.
It costs no upload at all: a message's own blobId is its RFC822 blob and
already lives in the account, so this goes through the same by-reference
path as attach-from-Files and a 40 MB message attaches as fast as a small
one.
It is in the message's own menu, the list's right-click menu, and the
overflow on the reply strip at the foot of a thread, which is the one a
thumb finds on a phone.
Two things fixed on the way, both exposed rather than introduced by this.
The filename rule was subject.replace(/[^\w.-]+/g, "_"), and \w without
the u flag is ASCII: every character of a Russian, Japanese or Chinese
subject failed the class, so those messages downloaded as a row of
underscores. What is actually unsafe in a filename is much shorter than
"not ASCII" -- path separators, the names Windows reserves, the control
range -- so the rule now keeps letters from any script and drops only
those. It lives in one place and the .eml download uses it too.
And the composer's attachment chip set overflow/text-overflow on a span,
where neither does anything, so the name never truncated and the size ran
on after it on the same line. Only long names showed it, which is every
.eml named from a subject.
Templates were a fixed subject and body, so anything that changed per
message -- who it is going to, today's date -- had to be typed over
afterwards.
Eight names are recognised: recipientName, recipientFirstName,
recipientEmail, myName, myEmail, subject, date and time. Dates and times
go through datetime.ts rather than toLocaleDateString, so a template
follows the date order and clock the app was already told to use.
Filling happens on insert rather than on send. What a placeholder came to
is then visible in the composer and can be edited, instead of the message
changing between writing it and sending it.
Two things are deliberately left alone. A placeholder that cannot be
answered yet -- a recipient's name on a draft nobody has addressed -- stays
in the body as written, because substituting an empty string produces
"Hi ,", which is wrong rather than visibly unfinished; leaving the name
says which word is still missing and can be typed over. And a name that is
not a placeholder is left as written too, since a body that quietly ate an
unrecognised token would be worse than one that shows it.
Values are escaped on the way into HTML: a display name comes from a
contact card or a typed address and is not trusted markup.
A mail the far end rejected, or one that went to an address with a typo in
it, is a mail you want to send again -- not forward, and not reply to.
Doing it by hand meant a new message and copying five fields across.
"Compose as new" sits with Reply and Forward, in the message menu and in
the list's right-click menu. It opens a composer holding the recipients
the message had, its Reply-To, its subject with nothing prefixed to it,
its body with nothing wrapped around it, and its attachments.
What makes it a new mail is what it leaves behind. `draftId` stays null,
or sending would destroy the message it was made from. `inReplyTo`,
`references`, `relatedEmailId` and `relatedKeyword` stay null, so it hangs
off no thread and sending it marks the original neither answered nor
forwarded. The Message-ID is the server's and the date is stamped at
build time, so both are new without anything asking for them -- the send
path needed no changes at all.
A message you sent is composed as the identity you sent it as. One
somebody else sent has no identity of yours to match, and guessing from
whom it was addressed to would put the resend behind an alias that was
only ever the receiving end, so that case takes the account's default.
No signature is added. The body is the one that was sent, which already
ends in whatever signature went with it, and appending the identity's
would give it two.
Closes#176
`i18n:coverage` reported 100% while a hundred-odd strings rendered
English in every language. It was not wrong about what it measured: it
reads JSX text, and none of these were JSX text. They were toast
arguments, `confirmDialog({ title, confirmLabel })` props, `title=` and
`aria-label=` attributes, and template literals — every one built from an
expression the codemod cannot read.
176 source strings and 15 plural sets now go through t() and plural(),
translated into all nine languages. Where English put a word in a slot,
the sentence is spelled out per branch instead: `Filter ${verb}` became
"Filter saved" and "Filter created", because which word agrees with what,
and where it sits, is not a property English gets to decide for everyone.
Counts that were `${n} message${n === 1 ? "" : "s"}` are plural() calls,
so Russian and Ukrainian get three forms and Japanese and Chinese get the
one they actually have.
Two of the catalogue's own conventions were worth learning the hard way.
Plural entries are keyed on the English *other* form, not `one` — `one`
is a form English happens to have and Japanese does not. And a constant
table holding English that is translated at the render site is fine: the
literal is a key, not a leak.
Which is what the new check encodes. `scripts/i18n-literals.mjs` accepts
a string that is wrapped where it is written or is a catalogue key
somewhere, and refuses one that is neither — a string no catalogue can
translate, however many languages ship. It found twenty more than my own
sweep had, including the stale-folder toast seen in production. It runs
as part of `npm run i18n:check`.
Also fixed: the catalogue is now awaited before the first paint. The
tree is rebuilt when a catalogue lands, so components recover on their
own, but a string computed in an effect does not — a toast fired in that
gap is emitted in English and stays English. The wait costs nothing
visible, since the session bootstrap already shows a spinner and English
resolves immediately.
And the Japanese agenda title loses a space Japanese does not use:
"{date} からの予定" was written with the English habit of spacing around
a placeholder.
Attaching meant uploading, even when the file was sitting in the account
already -- picking it off disk again to send the server a copy of what it
was holding.
The composer can now attach from Files. A blob the account can already
see needs no upload at all: an attachment carrying a `blobId` is what a
forward produces, so the send path has always known what to do with one.
Attaching a large file the server is already storing now costs nothing
and takes no time.
A file in an account somebody *shared* is different, because blobs belong
to the account they were uploaded to and a draft in yours cannot
reference one in theirs. Those are fetched and uploaded to your account,
and the picker says so before you attach rather than leaving someone
wondering why one file was instant and another was not.
The picker borrows the Files store, so it browses what Files browses,
shared accounts included, and puts the file manager back where it was on
the way out -- a detour through somebody's shared folder to find an
attachment should not leave Files somewhere else afterwards.
Verified against the mock, and worth recording how, because the first
attempt measured nothing: `client.upload` uses XMLHttpRequest, since it
reports progress, so a counter wrapped around `fetch` sees no uploads
whether or not any happen and agrees with you either way. Counted at
XHR instead: attaching one's own file issues no upload, and attaching a
shared one issues exactly one, to the reader's own account.
Scheduled send, which the README listed as needing server support that
Stalwart has had all along. The delay cannot be asked for directly --
RFC 8621 makes `sendAt` read-only and server-derived -- so it goes on the
envelope as an RFC 4865 `HOLDUNTIL` parameter, and the server reports back
the time it settled on.
Stalwart advertises this in the *account* capability, not the session-level
one (which is empty): `maxDelayedSend` of thirty days and `FUTURERELEASE`
among its `submissionExtensions`. The composer offers scheduling only when
both are there, and never offers a time the server would refuse.
A held message goes to a Scheduled folder rather than Sent, because
`onSuccessUpdateEmail` would otherwise file it as sent the moment the
submission is created, and it has not been sent. Nothing moves it out when
the hold expires, so the folder is reconciled on the way in: released
messages to Sent, cancelled ones back to Drafts. Cancelling uses a separate
`Email/set` rather than `onSuccessUpdateEmail`, whose key Stalwart reads as
an Email id and not, as the RFC says, a submission id.
The mock grows the whole lifecycle, and learns to resolve creation
references while it is there -- it had been quietly declining to create any
submission at all, since sending names its message as `#m`. Because
Stalwart's own `futureRelease` setting defaults to off and then drops the
hold in silence, `npm run dev:mock:no-future-release` reproduces that.
Verified end to end against the mock; not yet against the live server.
Every message ihasmail sent set cc, bcc and replyTo to null when unused, and
inReplyTo/references likewise on a new message. Stalwart parses those
properties with try_into_address_list, which returns None for null, and the
create is rejected outright:
if let Some(addresses) = value.try_into_address_list() { ... }
else { response.invalid_property_create(id, header); continue 'create; }
So every send failed with "Invalid property or value.", new messages and
replies alike, regardless of attachments or signature. The mock server
accepts anything, which is why this only showed up against a real server.
Empty header properties are now omitted. On a create there is no previous
value to clear, so null was never needed - only the properties actually being
set belong in the object.
buildEmailObject is exported so the shape can be tested directly, with a
regression test that no property is ever null.
"Send failed: Invalid property or value." is Stalwart's description for
invalidProperties, and on its own it says nothing about what to fix. The
SetError also carries a `properties` array naming the offending fields, which
every call site was discarding.
setErrorMessage appends them, and the 35 places that surfaced a SetError -
send, save draft, mailboxes, calendars, contacts, sieve, files, signature
images, sharing - now go through it.
Settings > General gains a "Default mail app" section that calls
registerProtocolHandler so mail links anywhere in the browser open ihasmail.
The browser owns the decision and there is no API to read it back, so the UI
says what it can: it records that we asked, offers "Ask again", shows a
Remove button where unregisterProtocolHandler exists, and points at the
browser's own settings. Unsupported browsers (Safari) and insecure contexts
get an explanation instead of a dead button.
The manifest now declares protocol_handlers for mailto, which is the route by
which an *installed* app can be offered by the operating system itself; the
UI says so and links the two ideas rather than promising a system-wide
default the page cannot grant.
Mailto parsing is now one function (parseMailto in lib/address.ts) instead of
three hand-rolled copies in AppShell and MessageView. It follows RFC 6068:
recipients from the path, the to= header or both, case-insensitive headers,
"+" as space, and tolerant of malformed escapes. That fixes Cc and Bcc being
silently dropped, and draftFromMailto escapes the body so a mailto: URL from
an untrusted page reaches the composer as text rather than markup.
