POP Mail Protocol
Detection Information
The following page provides information on the POP Mail Protocol.
Protocol Description
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.
Full Name
Post Office Protocol
Abbreviation
POP3
Introduced
Version 2.88
Best Practices
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.
