I just built a new Ipsconfig 3 server, using Centos 6.3 Perfect server instructions. I updated Ipsconfig afterwards. Everything seems to work fine, mail can come and go, webmail works, etc. But POP3 doesn't seem to work. When I use a mail client, such as Outlook, I can send mail, but it will not connect to Pop. I've tried Imap, same results. It can't connect to the server with a client. I don't know where to start to troubleshoot. If you can give me some ideas where to look I would appreciate it.
