- if the guessed hostname is not correct, you can specify one yourself. useful
if you generate a config locally and deploy to a different machine.
- if explicit public ips are found, check them with spamhaus and spamcop DNSBLs
and warn if they are listed, with links to check more DNSBLs. should prevent
disappointment later on.
- make it easier to run with an existing webserver. the quickstart now has a new option for that, it generates a different mox.conf, and further instructions such as configuring the tls keys/certs and reverse proxy urls. and changes to make autoconfig work in that case too.
- when starting up, request a tls cert for the hostname and for the autoconfig endpoint. the first will be requested soon anyway, and the autoconfig cert is needed early so the first autoconfig request doesn't time out (without helpful message to the user by at least thunderbird). and don't request the certificate before the servers are online. the root process was now requesting the certs, before the child process was serving on the tls port.
- add examples of configs generated by the quickstart.
- enable debug logging in config from quickstart, to give user more info.
for issue #5
- serve static files, serving index.html or optionally listings for directories
- redirects
- reverse-proxy, forwarding requests to a backend
these are configurable through the config file. a domain and path regexp have to
be configured. path prefixes can be stripped. configured domains are added to
the autotls allowlist, so acme automatically fetches certificates for them.
all webserver requests now have (access) logging, metrics, rate limiting.
on http errors, the error message prints an encrypted cid for relating with log files.
this also adds a new mechanism for example config files.
makes it easier to run on bsd's, where you cannot (easily?) let non-root users
bind to ports <1024. starting as root also paves the way for future improvements
with privilege separation.
unfortunately, this requires changes to how you start mox. though mox will help
by automatically fix up dir/file permissions/ownership.
if you start mox from the systemd unit file, you should update it so it starts
as root and adds a few additional capabilities:
# first update the mox binary, then, as root:
./mox config printservice >mox.service
systemctl daemon-reload
systemctl restart mox
journalctl -f -u mox &
# you should see mox start up, with messages about fixing permissions on dirs/files.
if you used the recommended config/ and data/ directory, in a directory just for
mox, and with the mox user called "mox", this should be enough.
if you don't want mox to modify dir/file permissions, set "NoFixPermissions:
true" in mox.conf.
if you named the mox user something else than mox, e.g. "_mox", add "User: _mox"
to mox.conf.
if you created a shared service user as originally suggested, you may want to
get rid of that as it is no longer useful and may get in the way. e.g. if you
had /home/service/mox with a "service" user, that service user can no longer
access any files: only mox and root can.
this also adds scripts for building mox docker images for alpine-supported
platforms.
the "restart" subcommand has been removed. it wasn't all that useful and got in
the way.
and another change: when adding a domain while mtasts isn't enabled, don't add
the per-domain mtasts config, as it would cause failure to add the domain.
based on report from setting up mox on openbsd from mteege.
and based on issue #3. thanks for the feedback!
so users can easily take their email out of somewhere else, and import it into mox.
this goes a little way to give feedback as the import progresses: upload
progress is shown (surprisingly, browsers aren't doing this...), imported
mailboxes/messages are counted (batched) and import issues/warnings are
displayed, all sent over an SSE connection. an import token is stored in
sessionstorage. if you reload the page (e.g. after a connection error), the
browser will reconnect to the running import and show its progress again. and
you can just abort the import before it is finished and committed, and nothing
will have changed.
this also imports flags/keywords from mbox files.
this matches how the quickstart recommends setting up mox.
i've been running "./mox -config/mox.conf" from there for admin commands, but
"mox" is enough now.
before, we used heuristics to decide when to train/untrain a message as junk or
nonjunk: the message had to be seen, be in certain mailboxes. then if a message
was marked as junk, it was junk. and otherwise it was nonjunk. this wasn't good
enough: you may want to keep some messages around as neither junk or nonjunk.
and that wasn't possible.
ideally, we would just look at the imap $Junk and $NotJunk flags. the problem
is that mail clients don't set these flags, or don't make it easy. thunderbird
can set the flags based on its own bayesian filter. it has a shortcut for
marking Junk and moving it to the junk folder (good), but the counterpart of
notjunk only marks a message as notjunk without showing in the UI that it was
marked as notjunk. there is also no "move and mark as notjunk" mechanism. e.g.
"archive" does not mark a message as notjunk. ios mail and mutt don't appear to
have any way to see or change the $Junk and $NotJunk flags.
what email clients do have is the ability to move messages to other
mailboxes/folders. so mox now has a mechanism that allows you to configure
mailboxes that automatically set $Junk or $NotJunk (or clear both) when a
message is moved/copied/delivered to that folder. e.g. a mailbox called junk or
spam or rejects marks its messags as junk. inbox, postmaster, dmarc, tlsrpt,
neutral* mark their messages as neither junk or notjunk. other folders mark
their messages as notjunk. e.g. list/*, archive. this functionality is
optional, but enabled with the quickstart and for new accounts.
also, mox now keeps track of the previous training of a message and will only
untrain/train if needed. before, there probably have been duplicate or missing
(un)trainings.
this also includes a new subcommand "retrain" to recreate the junkfilter for an
account. you should run it after updating to this version. and you should
probably also modify your account config to include the AutomaticJunkFlags.
- make the example commands in the readme more likely to succeed, especially
for people who are not familiar with go and its toolchain.
- improve probability that the correct configuration is generated, especially
the hostname. previously, if the quickstart email address was "some.domain",
and the machine where you ran the quickstart was "myhost", the hostname used
for the configuration was assumed to be "myhost.some.domain". but this is often
not correct, especially when configuring mox to serve mail on a subdomain of an
existing domain. mox will now try to determine the host name by a reverse
lookup of the public ips it found. and it will warn if there are no/multiple
candidates.
based on feedback from erik dubbelboer, thanks!
named "traceauth" and "tracedata".
with this, you can (almost) enable trace logging without fear of logging
sensitive data or ddos'ing your log server.
the caveat is that the imap login command has already printed the line as
regular trace before we can decide it should not be. can be fixed soon.
- when sendmail is invoked to sent to a local user, eg "root", send to a
configured defaultaddress instead. previously, we would fail printing usage.
- add a subcommand that prints the config file, /etc/moxsubmit.conf.
- follow the STARTTLS setting.
- fix running as just plain sendmail.
