Port 1666

Modified by:

Port 1666 is typically used for the Internet Message Access Protocol (IMAP), specifically for encrypted IMAP connections (IMAPS). IMAP is a protocol used by email clients to access and manage email messages stored on a mail server. IMAP allows users to access their email messages from multiple devices and stores the messages on the server, rather than downloading them to the local machine. IMAPS uses SSL/TLS encryption to secure the connection between the email client and the server.

Ports those registered with IANA are shown as official ports. The same port number may be unofficialy used by various services or applications. The official usage are listed separately below its usage may change from time to time.
