IMAP Mail Protocol
The following page provides information on the IMAP Mail Protocol.
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.
Internet Message Access Protocol
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.
- TCP 143 - IMAP mail port.
- TCP 993 - Secure IMAP mail port.
