IMAP Mail Protocol

Detection Information

The following page provides information on the IMAP Mail Protocol.

Protocol Description

The Internet Message Access Protocol (IMAP) protocol is used by e-mail clients to synchronize mail from a remote server. The more secure IMAPS protocol is more widely deployed, but IMAP is still in use.

Full Name

Internet Message Access Protocol

Abbreviation

IMAP

Introduced

Version 2.88

Best Practices

IMAP 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 IMAPS protocol to guarantee encryption.
