if files {webmail,webaccount,webadmin}.{css,js} exist in the configdir (where
the mox.conf file lives), their contents are included in the web apps.
the webmail now uses css variables, mostly for colors. so you can write a
custom webmail.css that changes the variables, e.g.:
:root {
--color: blue
}
you can also look at css class names and override their styles.
in the future, we may want to make some css variables configurable in the
per-user settings in the webmail. should reduce the number of variables first.
any custom javascript is loaded first. if it defines a global function
"moxBeforeDisplay", that is called each time a page loads (after
authentication) with the DOM element of the page content as parameter. the
webmail is a single persistent page. this can be used to make some changes to
the DOM, e.g. inserting some elements. we'll have to see how well this works in
practice. perhaps some patterns emerge (e.g. adding a logo), and we can make
those use-cases easier to achieve.
helps partially with issue #114, and based on questions from laura-lilly on
matrix.
the pointer events for moving the mouse would be consumed by the iframe. that
broke resizing of the compose popup. we now disable pointerevents on the main
ui when we are dragging the corner of the compose popup.
this is similar to an earlier change about the draggable split bar between the
message list and the message view (when showing an html message).
we kept the "save draft" promise, and would wait for it again for other
operations (eg close, save again, send), which wouldn't make progress.
can easily be reproduced by saving a message with a control character in an
address or the subject. saving the draft will fail.

since ios18, downloaded files don't go immediately to the settings (which is
somewhat understandable given potential for abuse), but go to the Files app.
opening them in the Files app then adds them to the settings where they can be
installed.
if admin has disabled mta-sts for a domain, we still check for records &
policies, but won't mark it as error when they don't exist. we do now keep
warning that mta-sts isn't enabled, otherwise we would start showing a green
"ok".
this also fixes the mta-sts code returning ErrNoPolicy when mtasts.<domain>
doesn't exist. the dns lookup is done with the reguler "net" package dns lookup
code, not through adns, so we look for two types of DNSError's.
noticed a while ago when testing with MTA-STS while debugging TLS connection
issues with MS.
was encountered during smtp session. but could also happen for imapserver and
webmail.
in smtpserver, we now log error messages for smtp errors that cause us to print
a stack trace. would have made logging output more helpful (without having to
turn on trace-level logging).
hopefully solves issue #238 by mwyvr, thanks for reporting!
and explain in more detail what it means in the webadmin interface.
will hopefully bring less confusion.
for issue #244 by exander77, thanks for reporting
"bodystructure" is like "body", but bodystructure allows returning more
information. we chose not to do that, initially because it was easier to
implement, and more recently because we can't easily return the additional
content-md5 field for leaf parts (since we don't have it in parsed form). but
now we just return the extended form for multiparts, and non-extended form for
leaf parts. likely no one would be looking for any content-md5-value for leaf
parts anyway. knowing the boundary is much more likely to be useful.
for issue #217 by danieleggert, thanks for reporting!
before this change, we were logging an empty string, which turned into "[]",
looking like an empty array. misleading and unhelpful.
this is fixed by making struct fields on type recipient "exported" so they can
get logged, and by changing the logging code to log nested
struct/pointer/interface fields if we would otherwise wouldn't log anything
(when only logging more basic data types).
we'll now get log lines like:
l=info m="deliver attempt to unknown user(s)" pkg=smtpserver recipients="[addr=bogus@test.example]"

before this change, when archiving, we would move all messages from the thread
that are in the same mailbox as that of the response message to the archive
mailbox. so if the message that was being responsed to was already in the
archive mailbox, the message would be moved from archive mailbox to archive
mailbox, resulting in an error.
with this change, when archiving, we move the thread messages that are in the
same mailbox as is currently open (independent of the mailbox the message lives
in, a common situation in the threading view). if there is no open mailbox
(search results), we still use the mailbox of the message being responded to as
reference.
with this new approach, we won't get errors moving a message to an archive
mailbox when it's already there. well, you can still get that error, but then
you've got the archive mailbox open, or you're in a search result and
responding to an archived message. the error should at least help understand
that nothing is happening.
we are only moving the messages from one active/reference mailbox because we
don't want to move messages from the thread that are in the Sent mailbox, and
we also don't want to move duplicate messages (cross-posts to mailing lists)
that are in other mailboxes. moving only the messages from the current active
mailbox seems safe, and should do what is what users would expect most of the
time.
for issue #233 by mattfbacon, thanks for reporting!
because this mechanism is most needed behind a reverse proxy, where acme
tls-alpn-01 won't work (because the reverse proxy won't pass on the alpn
extensions). if that's the case, there is obviously a webserver on port 443.
and it likely also running on port 80. so before this change, if tls-alpn-01
isn't available, http-01 also wasn't available, leaving no validation
mechanisms.
for issue #218 by mgkirs, thanks for reporting and details. hope this helps.
when we send a list of messages from the mox backend to the js frontend, we
include a parsed form of the "initial" message: the one we immediately show,
typically the top-most (unread) message. however, if that message could not be
parsed (due to invalid header syntax), we would fail the entire operation of
loading the view.
with this change, we simply don't return a parsed form of an initial message if
we cannot parse it. that will cause the webmail frontend to not select &
display a message immediately. if you then try to open the message, you'll
still get an error message as before. but at least the view has been loaded,
and you can open the raw message to inspect the contents.

not generating it yet from imapserver because we don't have content-md5
available. we could send "nil" instead of any actual content-md5 header (and
probably no contemporary messages include a content-md5 header), but it would
not be correct. if no known clients have problems in practice with absent
extensible data, it's better to just leave the bodystructure as is, with
extensible data.

we add various information while analysing an incoming message. like
dkim/spf/ip reputation. and content-based junk filter threshold/result and
ham/spam words used.

there is only an internet-draft about the required behaviour. it says clients
should ignore the strings. some clients do check the string. most servers
appear to use "Username:" and "Password:" as challenge. we'll follow them,
hoping to improve interoperability.
for issue #223 by gdunstone, and with analysis from wneessen of go-mail.
thanks!
this is a typical case if you made an alias to test how it works, with your
account. we may have to make this behaviour optional in the future.
for issue #220 by wneessen, thanks for reporting!
for some errors during the scram authentication protocol, we would treat some
errors that a client connection could induce as server errors, printing a stack
trace and aborting the connection.
this change recognizes those errors and sends regular "authentication failed"
or "protocol error" error messages to the client.
for issue #222 by wneessen, thanks for reporting
otherwise, if the recipient was a bcc, there's no good way to see why the
message was received.
incoming webhooks already have this rcptto field, but that's not always the
moment you want to process it.
for mattanja on matrix, thanks for reporting!
we didn't announce starttls as capability, but clients can still try them. we
would try to do a handshake with a nil certificate, which would cause a
goroutine panic (which is handled gracefully, shutting down the connection).
found with code that was doing starttls unconditionally.
these singleusetokens can be redeemed once. so when you see it in the logs, it
can't be used again. they are short-lived anyway.
this change should help prevent me periodically investigating token handling...
before, we would just say "session expired". now we say "session expired (after
12 hours inactivity)" (for admin) or "session expired (after 24 hours
inactivity)" for account/webmail. for unknown sessions in the admin interface,
we also explain that server restarts and 10 more new sessions can be the
reason.
for issue #202 by ally9335
since we have more of our own styling (probably since dark mode), we weren't
indicating anymore that a button was disabled. this actually only applies to
the button for the current mailbox of a message, when attempting to move it.
we now don't show any hover effects in that case, and we show the button
semitransparent.
