IMAP uses port 143
The IMAP (Internet Message Access Protocol) email protocol usually uses port 143.
IMAP port is the port number the IMAP protocol uses to transfer data. The standard IMAP Port number is 143
The standard port numbers for the specified protocols are as follows: SMTP (Simple Mail Transfer Protocol) uses port 25, POP3 (Post Office Protocol version 3) uses port 110, IMAP4 (Internet Message Access Protocol version 4) uses port 143, RPC (Remote Procedure Call) commonly uses port 135, LDAP (Lightweight Directory Access Protocol) operates on port 389, and the Global Catalog service typically uses port 3268. These ports facilitate various email and directory services in network communications.
IMAP (Internet Message Access Protocol) uses TCP (Transmission Control Protocol) for communication. The standard port for IMAP is 143, while the secure version, IMAPS, typically uses port 993. Unlike UDP, TCP provides a reliable connection, ensuring that messages are delivered in the correct order without loss.
To load up web pages we use the HTTP protocol which runs on port 80 and HTTPS port 443. Of course there are many more protocols than just that. I will list some below... For associating host names... DNS Port 53 For web based email. IMAP port 143

To send and receive email, the primary ports that need to be open are TCP port 25 for SMTP (Simple Mail Transfer Protocol) used for sending mail, and TCP port 143 for IMAP (Internet Message Access Protocol) or TCP port 110 for POP3 (Post Office Protocol) used for receiving mail. Additionally, secure connections often utilize TCP port 587 for SMTP with encryption and TCP port 993 for IMAP over SSL. Ensuring these ports are open allows for proper email communication.
The Live Mail server typically uses the following port numbers for email communication: for incoming mail (IMAP), it uses port 993 for SSL/TLS connections and port 143 for non-encrypted connections. For POP3, the server uses port 995 for secure connections and port 110 for non-encrypted ones. For outgoing mail (SMTP), it generally operates on port 587 for secure submissions and port 25 for non-encrypted transmissions.
21 port - FTP (File Transfer Protocol) 25 port - SMTP (Simple Mail Transfer Protocol) 110 port - POP3 (Post Office Protocol used by email clients) 80 port - HTTP (World wide web Portocol) Services: port 21- FTP, port 25- Secure shell, Port 80- Web Server and port 110-Web Server Protocol: port 21-FTP, port 25- SSH, port 80- HTTP and port 110- POP2
The default port number for the Internet Message Access Protocol (IMAP) is 143. When using IMAP over SSL/TLS for secure communication, the default port number is 993.
The Internet Message Access Port is commonly assigned to port numbers 143 and 993. If one has access rights to their email server, they can manually change their IMAP port numbers there.
