What is the standard port number for IMAP?

Explanation:
The standard port for IMAP is 143. This is the default TCP port that clients use to connect to an IMAP server for unencrypted mail retrieval and management. If you’re using IMAP over TLS/SSL, the secure port is 993, which is a separate, encrypted option. The other numbers correspond to different mail protocols: 110 is POP3, and 995 is POP3S (POP3 over SSL). So 143 is the correct choice for the standard, unencrypted IMAP port.
