- 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.
- CAP_FSETID looks needed to make accessing setgid dirs work.
- CAP_DAC_OVERRIDE CAP_DAC_READ_SEARCH are needed to access the existing config/mox.conf.
- CAP_FOWNER seems needed to chmod the config/ and data/ files.
- RestrictSUIDSGID=yes has to be off for chmod to work
because users may run this on their local machine, then copy the binary the
their server. there is a good chance that binary won't start on linux/amd64 when
compiled with cgo due to missing glibc symbols.
binaries for linux/amd64 were build for each target platform. apparently the
--platform in the first-stage overrides the $TARGET* variables of the build.
docker behaviour always manages to surprise me...
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!
import does its own batched junkfilter training, so the deliver function
doesn't have to do it one message at a time, writing the updated filter each
time. however, if the message cannot be parsed, it isn't trained during import,
and deliver would try to train it again. it would try to open the junk filter
to do so, but that would fail because the import function already has the
junkfilter open (and the timeout is reached). a missing error check would
continue with a nil junkfilter, resulting in the nil pointer deref.
this adds the missing error check, and makes sure the deliver function does not
also try to train unparseable imported messages.
report from Jens Hilligsøe
in the Dockerfile, allow running on privileged ports and expose those ports.
add a docker-compose.yml with instructions for the quickstart.
fix running imaptest somewhat. after a short while it will hit the rate limiter.
in quickstart, recognize we are running under docker, and print slightly
different commands to set permissions, and skip generating the systemd service
file. als fix cleaning up the right paths during failure in quickstart.
for issue #3
the error handling code attempts to collect all error messages it encounters,
to print them all at the end, so you can fix them all before trying again. so
we try to continue preparing the config after an error. in this case, we
continued as if acme.Manager was properly set and nil-dereferenced it.
for issue #2, from hismailbulut
so you can run mox on openbsd with port redirects in pf.conf.
in the future, starting as root, binding the sockets, and passing the bound
sockets to a new unprivileged process should be implemented, but this should
get openbsd users going.
from discussion with mteege
if you start delivering, openbsd's spamd will not announce 8bitmime support.
but once you get patched through to the actual mail server, it will likely
announce 8bitmime support.
perhaps we should also just attempt to deliver 8bit email without 8bitmime
extension. probably better for users than not even trying to send the message.
perhaps in a non-strict mode.
no need to not even try delivering in that case. if anyone is preventing mtasts
to work, nothing was achieved, because our fallback is the strictest behaviour
that could have been specified in the policy.
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.
