• Port 25: This is the default port for SMTP communication. It is used for transmitting emails between mail servers.
• Port 587: Also known as the submission port, this port is commonly used for email submission by email clients to mail servers.

These ports play a crucial role in ensuring smooth and efficient email communication. Understanding the common ports used in SMTP communication is essential for effectively managing email services.
