CentOS 7 uses firewalld. You'll need to enable the services you use 
(smtp, imap, and pop3) for the default zone. Something like:


firewall-cmd --zone=public --add-service=imap --permanent

firewall-cmd --zone=public --add-service=pop3 --permanent

firewall-cmd --zone=public --add-service=submission --permanent

firewall-cmd --zone=public --add-service=smtp --permanent
