I am trying to get a new server running but having problems because I don't understand which service is supposed to be controlling what as far as pop3 and imap go. I am running CentOS 4.4 and WHM 10.8.0 cPanel 10.8.1-R82. It seems that both cppop and couriertcpd want to control pop3. Whichever one starts first get's control of the port. If couriertcpd gets control then it checks the maildir for mail and cppop checks the inbox file for mail. Exim is routing the mail to the inbox file. Also it seems that couriertcpd is the only imap server. So to get everything working, I have to stop couriertcpd, start cppop, and then start couriertcpd. But my question is: how is it supposed to work?
