POP Mail Protocol
The Post Office Protocol (POP) is a protocol used by e-mail clients to retrieve mail from a remote server. The IMAP mail protocol is much more prevalent these days, but the protocol is still in use.
Post Office Protocol
POP3 is unencrypted, so usernames and passwords are sent across the network in clear text. If you see the POP3 protocol on your network, you should encourage the use of the alternative secure POP (POPS) protocol.
- TCP 110 - POP3 mail port.
- TCP 995 - Secure POP3 mail port.
