POP3 – By default, the POP3 protocol works on two ports :

IMAP – By default, the IMAP protocol works on two ports:

• Port 143 – this is the default IMAP non-encrypted port
• Port 993 – this is the port you need to use if you want to connect using IMAP securely

Note : if you use port No. 993 for IMAP or port No. 995 for POP3, you must change ‘Use the following type of encrypted connection’ from None to SSL.
