What are the mailserver ports?

Secure POP3 is on port 995
Non-secure POP3 is on port 110

Secure SMTP is on port 465
Non-secure SMTP is on port 25 (with a second option of using port 26 if your ISP blocks port 25)

Secure IMAP is on port 993
Non-secure IMAP is on port 143

In all cases we recommend use the of the secure port in
preference to the non-secure.
