System stopped sending e-mail messages.

Hi,

I've been using FreeBSD for a while but I really have never checked log messages or anything like that (I know, shame on me). So today I decided to check my mail (in /var/mail/someuser). I noticed that I had 19 new messages, so I checked all of them and everything seemed to be working just fine. But here's the problem: About a month ago, I changed the hostname of this machine, and I noticed that every since I changed hostnames, I've never got any new mail from the system. So the last message I got, is from about a month ago, and it was sent to my old hostname, while I've never got any new mail to the new hostname.

What could be going on?

Read through /var/log/maillog to see.

In addition, the output of mailq(1) might be useful.

Thanks for the replies!

On my original post I left out a BIG part of what I have done that could explain why I'm not getting any mail from the system.

I have actually switched MTA. I stopped using sendmail and now I have postfix up and running (this was done at the same time that I changed hostname).

I'm able to receive/send mail just fine. I use virtual mail boxes, and I actually use roundcube to send and check mail messages (which is working very good ). Yesterday I used the "mail" command to send an e-mail from the root user to my gmail account, and this also worked just fine. But whenever I try to send an e-mail to root@localhost I don't receive anything.

Here's one of the messages in maillog: to=<root@myhost.mydomain>, relay=none, delay=0.58, delays=0.01/0.04/0.53/0, dsn=5.4.6, status=bounced (mail for myhost.mydomain loops back to myself).

I also checked mail queue and its empty.

I'm almost sure that this problem happened when I switched MTA. Any new ideas on this problem?

Check myhostname, mydomain, and mydestination variables in /usr/local/etc/postfix/main.cf. The comments around those will explain what's wrong.
