the members must currently all be addresses of local accounts.
a message sent to an alias is accepted if at least one of the members accepts
it. if no members accepts it (e.g. due to bad reputation of sender), the
message is rejected.
if a message is submitted to both an alias addresses and to recipients that are
members of the alias in an smtp transaction, the message will be delivered to
such members only once. the same applies if the address in the message
from-header is the address of a member: that member won't receive the message
(they sent it). this prevents duplicate messages.
aliases have three configuration options:
- PostPublic: whether anyone can send through the alias, or only members.
members-only lists can be useful inside organizations for internal
communication. public lists can be useful for support addresses.
- ListMembers: whether members can see the addresses of other members. this can
be seen in the account web interface. in the future, we could export this in
other ways, so clients can expand the list.
- AllowMsgFrom: whether messages can be sent through the alias with the alias
address used in the message from-header. the webmail knows it can use that
address, and will use it as from-address when replying to a message sent to
that address.
ideas for the future:
- allow external addresses as members. still with some restrictions, such as
requiring a valid dkim-signature so delivery has a chance to succeed. will
also need configuration of an admin that can receive any bounces.
- allow specifying specific members who can sent through the list (instead of
all members).

thanks to damir & marin from sartura for discussing requirements/features.
instead of skipping on any smtp and delivering messages to accounts.
we dial the ip of the smtp listener, which is localhost:1025 by default.
the smtp server now uses a mock dns resolver during spf & dkim verification for
hosted domains (localhost by default), so they should pass.
the advantage is that we get regular full smtp server behaviour for delivering
in localserve, including webhooks, and potential first-time sender delays
(though this is disabled by default now).
incoming deliveries now go through normal address resolution, where before we
would always deliver to mox@localhost. we still accept email for unknown
recipients to mox@localhost.
this will be useful upcoming alias/list functionality.
localserve will now generate a dkim key when creating a new config. existing
users may wish to reset (remove) their localserve directory, or add a dkim key.
per mailbox, or for all mailboxes, in maildir/mbox format, in tar/tgz/zip
archive or without archive format for single mbox, single or recursive. the
webaccount already had an option to export all mailboxes, it now looks similar
to the webmail version.
if the message has a list-id header, we assume this is a (mailing) list
message, and we require a dkim/spf-verified domain (we prefer the shortest that
is a suffix of the list-id value). the rule we would add will mark such
messages as from a mailing list, changing filtering rules on incoming messages
(not enforcing dmarc policies). messages will be matched on list-id header and
will only match if they have the same dkim/spf-verified domain.
if the message doesn't have a list-id header, we'll ask to match based on
"message from" address.
we don't ask the user in several cases:
- if the destination/source mailbox is a special-use mailbox (e.g.
trash,archive,sent,junk; inbox isn't included)
- if the rule already exist (no point in adding it again).
- if the user said "no, not for this list-id/from-address" in the past.
- if the user said "no, not for messages moved to this mailbox" in the past.
we'll add the rule if the message was moved out of the inbox.
if the message was moved to the inbox, we check if there is a matching rule
that we can remove.
we now remember the "no" answers (for list-id, msg-from-addr and mailbox) in
the account database.
to implement the msgfrom rules, this adds support to rulesets for matching on
message "from" address. before, we could match on smtp from address (and other
fields). rulesets now also have a field for comments. webmail adds a note that
it created the rule, with the date.
manual editing of the rulesets is still in the webaccount page. this webmail
functionality is just a convenient way to add/remove common rules.
in top-left direction. keep textarea filling the height.
remember size in localstorage, only apply either width and/or height when
viewport width/height was the same as when the remembered width/height was set
(independently).
no visual indicator other than a cursor indicating resizability.
the regular send shortcut is control+Enter. the shift enables "archive thread".
there is no configuration option, you'll always get the button, but only for
reply/forward, not for new compose.
we may do "send and move thread to thrash", but let's wait until people want it.
for github issue #135 by mattfbacon
the stuttering was introduced to make the same type name declared in multiple
packages, and used in the admin sherpa api, unique. with sherpadoc's new
rename, we can make them unique when generating the api definition/docs, and
the Go code can use nicer names.
for dmarc reporting address, tls reporting address, mtasts policy, dkim keys/selectors.
should make it easier for webadmin-using admins to discover these settings.
the webadmin interface is now on par with functionality you would set through
the configuration file, let's keep it that way.
this simplifies some of the code that makes modifications to the config file. a
few protected functions can make changes to the dynamic config, which webadmin
can use. instead of having separate functions in mox-/admin.go for each type of
change.
this also exports the parsed full dynamic config to webadmin, so we need fewer
functions for specific config fields too.
when sending a message with bcc's, prepend the bcc header to the message we
store in the sent folder. still not in the message we send to the recipients.
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.
for issue #31 by cuu508
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.
