E-mail abruptly stopped working...

Well, its a new week and I guess its time for a new problem, my server thought :(.

This time I have no clear idea of what is going wrong. I checked the logs and the only strange thing I get is this:

Aug 13 14:33:07 vps590 postfix/postqueue[31897]: warning: Mail system is down – accessing queue directly

I am not able to recieve mail, but I do not get a delivery failed message when I try to send something to myself via my gmail account. I am not able to send anything, I get a SMTP connection failed message. Webmail login is still working normally.

I did the hostname lookup, and that is still working normally as well. That is why I am completly lost. What can I do, reinstall the Postfix server?

The system is CentOS 6 64bit, running on Linux kernel 3.2.


What is the output of these two commands:

rpm -qa | grep postfix postconf -n

Hopefully those will shed some light on what’s going on!


First command:

[root@vps590 ~]# rpm -qa | grep postfix

Thanks again Eric :).

Hmm, I don’t see any obvious problems with that.

Can you try running this command:

/etc/init.d/postfix restart

And after that, take a peek in /var/log/maillog to see if any errors show up?


And it works again for now ;). The restart in PuTTy probably did the job. It acted a bit strange at first, it said [failed] at restart twice, but the third time it did restart normally.

I only restarted it via the virtualmin GUI before.
