Why tell anyone here are the ports you will need to have open when all they have specified is services? Wouldn't it have been better to ask IF they wanted pop3/pop3s/imap/imaps before telling them to open xyz ports? I'm not trying to be a dick, but get the facts before telling someone to open xyz ports. Why should they open pop3 to the world if they are going to use imap, or vice-versa; heck why open them to the world at all if they are going to use webmail and imap and pop3 access are only required from the webserver? I've set up many mail servers where the only service available to the world is smtp, port 25, and http/https. Why open the door further than it needs to be?
I wasn't trying to give him advice on how to run his E-mail setup.
The listing of the ports was just an example to help illustrate why running a firewall in front of an E-mail server is typically pointless.
I apologize if that wasn't clear.
