OK. The ports for POP3 are 110 incoming and port 25 or 26 for outgoing.

What other ports can be used for POP3. SSL and non SSL.

What are the ports for IMAP? Both SSL and non SSL?

Here is a brief list of the common mail-related ports:
cPanel Webmail, 2095
cPanel Webmail (SSL), 2096
IMAP, 143
IMAP (SSL), 993
POP, 110
POP (SSL), 995
SMTP, 25
SMTP (SSL), 465

As you mentioned, SMTP may have alternate ports depending on customizations to the configuration; the two alternates I see used most often are ports 26 and 587.

For a more verbose listing I would also reference the following entry in our documentation FAQ: Linux FAQ - Which ports should be open if I'm running my cPanel server behind a firewall?
