by default 1000 messages per day, and to max 200 first-time receivers.
i don't think a person would reach those limits. a compromised account abused
by spammers could easily reach that limit. this prevents further damage.
the error message you will get is quite clear, pointing to the configuration
parameter that should be changed.
current behaviour isn't intuitive. it's not great to have to attempt parsing
the strings as both localpart and email address. so we deprecate the
localpart-only behaviour. when we load the config file, and it has
localpart-only Destinations keys, we'll change them to full addresses in
memory. when an admin causes a write of domains.conf, it'll automatically be
fixed. we log an error with a deprecated notice for each localpart-only
destinations key.
sometime in the future, we can remove the old localpart-only destination
support. will be in the release notes then.
also start keeping track of update notes that need to make it in the release
notes of the next release.
for issue #18
- 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!
the previous default, marking the messages as junk had the interesting effect
of training the junk filter. rejecting could have been the result of the
sending IP being in the DNSBL. so the DNSBL helped to automatically train the
junk filter. perhaps we can keep that in the future and just not take messages
from the rejects mailbox into account when evaluating the reputation for
incoming deliveries.
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.
for example, by matching incoming messags on smtp mail from, verified domains
(spf/dkim), headers. then delivering to a configured mailbox. for mailing
lists, if a verified domain matches, regular spam checks can be skipped.
this was already possible by editing the configuration file, but only admins
can edit that file. now users can manage their own rulesets.
- 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!
- and don't have a global variable "d" in the big checkDomain function in http/admin.go.
- and set loglevel from command-line flag again after loading the config file, for all subcommands except "serve".
