Email protocols explained :

For those who want a simple explanation for e-mail ports and protocols here it is :

PORT 25 TCP : SMTP
PORT 110 TCP : POP3
Port 143 TCP : IMAP
Port 465 TCP : SMTPS (SSL)
Port 587 TCP : alternate SMTP, sometimes used if your ISP blocks port 25
Port 993 TCP : IMAPS (SSL)
Port 995 TCP : POP3S / POP3 TLS/SSL

SSL has it’s own ports : 465 or 993.

Examples of use :

Gmail.com :
SMTP 465 SSL / TLS
IMAP 993 SSL / TLS
