I have Webmin/Virtualmin running on Cent OS5 and everything seems fine, except that if I send mail (from webmail or POP3 account) it states sent, but is going into the server mailqueue. Have tried flush, but get this error:/usr/sbin/postqueue -c /etc/postfix -f .. postqueue: fatal: Cannot flush mail queue - mail system is down
But the Postfix server is running. Also Dovecot is running.
Also I cannot receiving any email from anyone, even localhost sent from webmail.
telnet localhost 110 Trying 127.0.0.1... Connected to localhost.secureserver.net (127.0.0.1). Escape character is '^]'. +OK Dovecot ready. user xxxx.shoots +OK pass XXXXX +OK Logged in. quit +OK Logging out.
telnet shoots.com 110 Trying 208.109.126.xxx... Connected to shoots.com (208.109.126.xxx). Escape character is '^]'. +OK Dovecot ready. user xxxx.shoots +OK pass XXXX +OK Logged in. quit +OK Logging out.
Connections look good. I've been at this for two days and can't get anything to work. HELP!!!
Any ideas??
Howdy,
Rather than Dovecot, it's Postfix that you'll want to look into.
Postfix is made up of a number of different processes, so if there's a configuration problem of some kind, it can look like it's up and running, even when one of it's processes is down.
What I'd suggest is restarting Postfix (using "/etc/init.d/postfix restart"), then take a peek in the email log to see if any errors show up. The email log is located in /var/log/maillog.

Have tried the restart a few times, have stopped everything, restarted and even rebooted the server.
The only thing in the maillog is:

Hrm, it sounds like the error is saying there's a "notify_classes" line setup that's invalid.
If you run "postconf -n", what output do you receive?

That doesn't strike me as particularly odd... what about if you run this command, do you get any output:
grep notify_classes /etc/postfix/*Perhaps one of the other config files is using that.

/etc/postfix/main.cf.default:notify_classes = resource, software

I was just looking at the maillogs - the mail is being processed, but it isn't going anywhere. Nothing in webmail account or via POP3 but lots in the queue. Look at the Dovecot reference.

Have found something strange - any ideas?
I have created 3 mail user accounts, but there are no physical mailboxes created in the MailDir directory in the $HOME/Maildir/ or in /var/mail - but the mail users exist in Virtualmin. That would explain why all of the mail (in and out) is accumulating in the postfix mail queue.
If anyone has some brilliant idea as to what is causing this error - I'd love to hear as I'm in email limbo. Have tried changing MailDir settings, nothing. Could be a permissions problem, but where. This is a fresh install from install.sh.
David Calderwood - Euro-Pacific Digital Media
I tried turning off postfix, uninstalled and did a fresh install. Still can't get the stupid POstfix to work. Driving me up the wall. The online documentation is really bad and does not refer to Centos5 versions.
I set everything to default:
BIND DNS server is installed, and the system is configured to use it. A problem was found with your Postfix virtual maps : No map sources were found in the Postfix configuration
.. your system is not ready for use by Virtualmin.
