I am on the Labs distribution rather than 9front but I use plan9 as my mail
server.

I have 3 seperate rules in rewrite:
# your local names
\l!(.*) alias \1
quintile\.net!(.*) alias \1
\l\.quintile\.net!(.*) alias \1

I tweek the standard rules a little to ease debugging:
echo /bin/upas/smtp -h $fd $addr $sender $* > /mail/tmp/rem.cli
exec /bin/upas/smtp -h $fd $addr $sender $* >[2] /mail/tmp/rem.err
/mail/tmp is useful as it is always there (not just bound by your profile,
and writable by the user none.
I send through a mail gateway (necessary these days as many smtp servers insist
the email comes from the remote server's MX relay.
The gateway address comes from the smtp= entry in /lib/ndb/local

you don't need a certificate to send email, but the fingerprint (checksom) of
your
mail relay's certificate is stored on plan9 to ensure there is not man in the
middle.
This lives in /sys/lib/tls/smtp and looks like
x509 sha1=CE3A0D3EDA4B77A353C09EA865B7F8C209714341
You can have several entries if your mail relay is multiple
machines hiding behind a single dns name,
The easist way is to just try and send some mail and it should fail with
an error "unknown fingerprint" but also listing the fingerprint. if you add
this to /sys/lib/tls/smtp your next attempt should work.

You only need to start auth/cron. My /cron/upas/cron has the following entries:
# kick mail retries (replace mailserver with your system)
0,30 * * * * local /bin/upas/runq -a /mail/queue
/mail/lib/remotemail
# broadcast news
3 6 * * * local /mail/lib/mailnews
# clean up after grey list
47 4 * * * local rm -rf /mail/grey/tmp/*/*
I have a compined auth/file/cpu server so all the above run on the host
'local' if you have a bigger setup your config may change.
for a different and probably still correct the labs mail setup is detailed in
the wiki here: https://9p.io/wiki/plan9/mail_configuration/index.html
You are best using the 9front faq where that is clear but a 2nd opinion may
help if it is confusing.

Previously I was using OpenSMTPD on OpenBSD for my smtpd server, but I thought
I'd try the 9front smtpd server, but I have some questions if anyone would care
to indulge me in getting it setup for multiple domains to accept and send mail.
Under
7.7 - Mail server configuration and maintenance
7.7.1
For the smtpd.conf file the line would read:
ourdomains domain1.org, domain2.net, domain3.com
7.7.2
For the rewrie, the line would read:
(ttr|domain1.org|domain2.net|domain3.com)!(.*) alias \2
7.7.4
remotemail is where I am a little lost in what to use for multiple domains:
7.7.5 SMTP over TLS
Do I create a certificate for each domain?
Lastly, what do I enter in /cfg/$sysname/cpustart to start smtpd each time the
server boots?
Thanks for any help and I apologize for my ignorance.
