POP Mail Protocol
The following page provides information on the 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
POP can be both encrypted (via STARTTLS) and unencrypted, so there is a risk that usernames and passwords are sent across the network in an insecure manner. You might want to consider using the alternative POP3S protocol to guarantee encryption.
- TCP 110 - POP3 mail port.
- TCP 995 - Secure POP3 mail port.
