I followed the perfect setup walkthrough and created 4 domains with multiple accounts. The server ran fine for a few days, but now all mail is stuck in the mailqueue If I look in the postfix queue I see.. delivery temporarily suspended: connect to simba.computersaustin.com[24.227.164.226]: Connection timed out pinging simba.computersaustin.com results in replies from localhost
The error message means that the mail server on simba.computersaustin.com can not be reached. Maybe the mail server on the host simba.computersaustin.com is stopped or port 21 is blocked on a firewall. If you host your server at home, it might be that your access provider blocked port 21.
I am looking on the mailqueue in simba using webmin. so it can't connect to itself I am able to get mail into the primary domain.

Please make sure that the domain simba.computersaustin.com is registered in dns and points to your server IP address. Also change the line: mydomain = computersaustin.com to: mydomain = simba.computersaustin.com in postfix main.cf and restart postfix.
