I need to setup a small mail server on a local network. It only needs SMTP ability as it's just so Asterisk can send out emails. The machine has sendmail installed. My primary mail server seems to be rejecting the messages. Some research says something isn't configured properly. What do I have to do so the outside world accepts emails from my Asterisk box? It is behind a NAT.

Through help from people on the lists and then further investigation based on those results, here is what I did.

1) I set the office to a statically assigned IP instead of from the pool.
2) I made an A entry on one of my domains aiur.ics-il.net (where aiur is the machine name).
3) I added aiur.ics-il.net directly after 127.0.0.1 in the /etc/hosts file (copied below).
4) I set the from email address (serveremail) in /etc/asterisk/voicemail.conf to something at the domain I created (voicemail at aiur.ics-il.net).
5) Presto!

[root at Aiur ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 aiur.ics-il.net Aiur localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

I am the ISP.

I'll have to look into that smarthost deal as there is no reverse DNS at
this time (my upstream's server times out).

How would you relay on Google Apps, as Google requires SSL or TLS
authentication?

How can I configure sendmail to do this?
Actually, sendmail is trying to send email directly, and I get the response
below. I?ll now try Mike Hammett?s solution.

Thanks,

well, maybe ou're on the wrong list (talkin sendmail in an asterisk list
!!!) you're better in sendmail's list.

anyway, you need to modify sendmail.cf file, just a few tweaks & it will be
ok. you will need a smarthost, what is a smarthost ? thats an smtp server
that is allowed to send mail to the world, without it you can't send mail, &
this smarthost will be your isp's smtp server & noone else's unless you know
a lot of ppl around. otherwise your mails will get nowhere.

if you need an sendmail.cf file example i can paste it for you here.
also dovecot.conf will be valuable for you.
hope this helps.

Or maybe you can show him some links
Try this for send mail:
http://docs.snake.de/smtp-auth.html

this is very common these days and to make it more fun each mailserver
(provider) has their own criteria to decide if your email is spam or not.
to give you and example:
make sure you are using static public IP address for outgoing mails, have a
PTR record for that IP and also A record for the fqn that those mails are
coming from.
For smtp auth you need to have saslauth in place and most recent sendmails
are compile with saslauth these days.
I did not have 100% success with smtp and sasl and i believe that was caused
due to have different TLS versions.
anyway that link should put you in the right direction and if anyone else
has a better/easier mta that handles smarthost and auth flawlessly, please
comment.
