the cookies are set with a specific path, because the webadmin, webaccount and
webmail cookies can be on the same domain (this is the default). if the reverse
proxy strips the path while forwarding, the browser won't set the cookie and
the login attempt will fail.
based on github issue #151 from naturalethic
time.Now() returns a timestamp with timezone Local. if you marshal & unmarshal
it again, it'll get the Local timezone again. unless the local timezone is UTC.
then it will get the UTC timezone. the same time.Time but with explicit UTC
timezone vs explicit UTC-as-Local timezone are not the same when comparing with
==. so comparison should be done with time.Time.Equal, or comparison should be
done after having called .Local() on parsed timestamps (so the explicit UTC
timezone gets converted to the UTC-as-Local timezone). somewhat surprising that
time.Local isn't the same as time.UTC if TZ=/TZ=UTC. there are warnings
throughout the time package about handling of UTC.
for applications to compose/send messages, receive delivery feedback, and
maintain suppression lists.
this is an alternative to applications using a library to compose messages,
submitting those messages using smtp, and monitoring a mailbox with imap for
DSNs, which can be processed into the equivalent of suppression lists. but you
need to know about all these standards/protocols and find libraries. by using
the webapi & webhooks, you just need a http & json library.
unfortunately, there is no standard for these kinds of api, so mox has made up
yet another one...
matching incoming DSNs about deliveries to original outgoing messages requires
keeping history of "retired" messages (delivered from the queue, either
successfully or failed). this can be enabled per account. history is also
useful for debugging deliveries. we now also keep history of each delivery
attempt, accessible while still in the queue, and kept when a message is
retired. the queue webadmin pages now also have pagination, to show potentially
large history.
a queue of webhook calls is now managed too. failures are retried similar to
message deliveries. webhooks can also be saved to the retired list after
completing. also configurable per account.
messages can be sent with a "unique smtp mail from" address. this can only be
used if the domain is configured with a localpart catchall separator such as
"+". when enabled, a queued message gets assigned a random "fromid", which is
added after the separator when sending. when DSNs are returned, they can be
related to previously sent messages based on this fromid. in the future, we can
implement matching on the "envid" used in the smtp dsn extension, or on the
"message-id" of the message. using a fromid can be triggered by authenticating
with a login email address that is configured as enabling fromid.
suppression lists are automatically managed per account. if a delivery attempt
results in certain smtp errors, the destination address is added to the
suppression list. future messages queued for that recipient will immediately
fail without a delivery attempt. suppression lists protect your mail server
reputation.
submitted messages can carry "extra" data through the queue and webhooks for
outgoing deliveries. through webapi as a json object, through smtp submission
as message headers of the form "x-mox-extra-<key>: value".
to make it easy to test webapi/webhooks locally, the "localserve" mode actually
puts messages in the queue. when it's time to deliver, it still won't do a full
delivery attempt, but just delivers to the sender account. unless the recipient
address has a special form, simulating a failure to deliver.
admins now have more control over the queue. "hold rules" can be added to mark
newly queued messages as "on hold", pausing delivery. rules can be about
certain sender or recipient domains/addresses, or apply to all messages pausing
the entire queue. also useful for (local) testing.
new config options have been introduced. they are editable through the admin
and/or account web interfaces.
the webapi http endpoints are enabled for newly generated configs with the
quickstart, and in localserve. existing configurations must explicitly enable
the webapi in mox.conf.
gopherwatch.org was created to dogfood this code. it initially used just the
compose/smtpclient/imapclient mox packages to send messages and process
delivery feedback. it will get a config option to use the mox webapi/webhooks
instead. the gopherwatch code to use webapi/webhook is smaller and simpler, and
developing that shaped development of the mox webapi/webhooks.

in the precis password change before the previous release, the password used in
fuzzing wasn't correct, triggering sleeps due to botched protocols often, which
made the tests run much longer.
typescript now knows the full types, not just "any" for account config.
inline structs previously in config.Account are given their own type definition
so sherpa can generate types.
also update to latest sherpa lib that knows about time.Duration, to be used soon.
mox was already giving another try for received errors after the
`HELO`/`EHLO` command. Now mox do the same for received errors when
trying to deliver the message to the remote SMTP server.
This should help to deliver messages to SMTP server that rejects
incoming messages because of bad ipv4 or ipv6 configuration (for example
for servers checking reverse DNS records). mox will now try to deliver
messages on both ip family instead before considering the error as
permanent.
fix#149
The `TransportDirect` transport allows to tweak outgoing SMTP
connections to remote servers. Currently, it only allows to select
network IP family (ipv4, ipv6 or both).
For example, to disable ipv6 for all outgoing SMTP connections:
- add these lines in mox.conf to create a new transport named
"disableipv6":
```
Transports:
disableipv6:
Direct:
DisableIpv6: true
```
- then add these lines in domains.conf to use this transport:
```
Routes:
-
Transport: disableipv6
```
fix#149
because let's encrypt won't create an account for contact addresses with non-ascii characters.
we'll get an error message like:
400 urn:ietf:params:acme:error:invalidContact: Error creating new account :: contact email [\"mailto:...\"] contains non-ASCII characters
found & reported by arnt, thanks!
despite the name, it doesn't actually check for valid email addresses:
it doesn't allow non-ascii localparts, accepts various invalid localparts, and
rejects various valid localparts. no point in using it.
we include the username in session cookie values. but cookie values must be ascii-only, go's net/http's drops bad values. the typical solution is to querystring-encode/decode the cookie values, which we'll now do.
problem found by arnt, thanks for reporting!
don't treat just any number from filename as timestamp. require it has 2 dots.
prevents filenames with just a number as being seen as a timestamp, like when
you import files from a mox accounts msgs directory.
more useful than the time.Time zero file in case the maildir filename isn't
properly formed with a timestamp. this is not too uncommon when people
reconstruct maildirs from other sources of message files to then import the
maildir.

fix#145
- add option to put messages in the queue "on hold", preventing delivery
attempts until taken off hold again.
- add "hold rules", to automatically mark some/all submitted messages as "on
hold", e.g. from a specific account or to a specific domain.
- add operation to "fail" a message, causing a DSN to be delivered to the
sender. previously we could only drop a message from the queue.
- update admin page & add new cli tools for these operations, with new
filtering rules for selecting the messages to operate on. in the admin
interface, add filtering and checkboxes to select a set of messages to operate
on.
it is a remnant from the time domains didn't have to be specific in
"Destination" addresses. we still use it for as default selection for adding a
new address to an account. but there's not much point in showing it so
prominently. that raises more questions than it is helpful.
for issue #142 by tabatinga0xffff
we only have a "storage" limit. for total disk usage. we don't have a limit on
messages (count) or mailboxes (count). also not on total annotation size, but
we don't have support annotations at all at the moment.
we don't implement setquota. with rfc 9208 that's allowed. with the previous
quota rfc 2087 it wasn't.
the status command can now return "DELETED-STORAGE". which should be the disk
space that can be reclaimed by removing messages with the \Deleted flags.
however, it's not very likely clients set the \Deleted flag without expunging
the message immediately. we don't want to go through all messages to calculate
the sum of message sizes with the deleted flag. we also don't currently track
that in MailboxCount. so we just respond with "0". not compliant, but let's
wait until someone complains.
when returning quota information, it is not possible to give the current usage
when no limit is configured. clients implementing rfc 9208 should probably
conclude from the presence of QUOTA=RES-* capabilities (only in rfc 9208, not
in 2087) and the absence of those limits in quota responses (or the absence of
an untagged quota response at all) that a resource type doesn't have a limit.
thunderbird will claim there is no quota information when no limit was
configured, so we can probably conclude that it implements rfc 2087, but not
rfc 9208.
we now also show the usage & limit on the account page.
