Mail Program Port Numbers

Port numbers should be assigned by your mail program automatically based on your choices of IMAP vs POP3 and Encrypted vs Unencrypted.  Here are the most common:

 

POP3 (receiving mail), Encrypted SSL/TLS: 995

POP3 (receiving mail), Unencrypted (no SSL/TLS): 110

IMAP (receiving mail), Encrypted SSL/TLS: 993

IMAP (receiving mail), Unencrypted (no SSL/TLS): 143

SMTP (sending mail), Encrypted SSL/TLS: 465

SMTP (sending mail), Unencrypted (no SSL/TLS): 26

 

Keep in mind if the port numbers in your mail program do not match your IMAP/POP3/Encrypted/Unencrypted choices, then the program will fail to connect.
