with tls with acme (with pebble, a small acme server for testing), and with
pregenerated keys/certs.
the two mox instances are configured on their own domain. we launch a separate
test container that connects to the first, submits a message for delivery to
the second. we check if the message is delivered with an imap connection and
the idle command.
when setting up the docker organization account for mox it already felt off.
depending on such a party to serve binaries didn't feel great to begin with.
after clarifying online discussions of docker's vague announcement of removing
free team organizations it was clearly time to move off hub.docker.com. best to
self-host.
r.xmox.nl is hosted with the new github.com/mjl-/vex.
pinging issue #3
- 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
- make builtin http handlers serve on specific domains, such as for mta-sts, so
e.g. /.well-known/mta-sts.txt isn't served on all domains.
- add logging of a few more fields in access logging.
- small tweaks/bug fixes in webserver request handling.
- add config option for redirecting entire domains to another (common enough).
- split httpserver metric into two: one for duration until writing header (i.e.
performance of server), another for duration until full response is sent to
client (i.e. performance as perceived by users).
- add admin ui, a new page for managing the configs. after making changes
and hitting "save", the changes take effect immediately. the page itself
doesn't look very well-designed (many input fields, makes it look messy). i
have an idea to improve it (explained in admin.html as todo) by making the
layout look just like the config file. not urgent though.
i've already changed my websites/webapps over.
the idea of adding a webserver is to take away a (the) reason for folks to want
to complicate their mox setup by running an other webserver on the same machine.
i think the current webserver implementation can already serve most common use
cases. with a few more tweaks (feedback needed!) we should be able to get to 95%
of the use cases. the reverse proxy can take care of the remaining 5%.
nevertheless, a next step is still to change the quickstart to make it easier
for folks to run with an existing webserver, with existing tls certs/keys.
that's how this relates to issue #5.
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!
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
