Question: 1 / 400

What is the typical port number for SMTP?

Port 80

Port 25

The typical port number for SMTP, which stands for Simple Mail Transfer Protocol, is 25. This port is primarily used for sending emails between servers and is the standard communication channel used by email service providers to route emails across the internet. When an email is sent, it typically travels over port 25 to reach the destination mail server.

Each of the other ports listed serves different purposes: Port 80 is used for HTTP traffic, which is the protocol for web pages; Port 110 is used for retrieving emails via the Post Office Protocol (POP3); and Port 443 is used for HTTPS, which is HTTP over SSL/TLS for secure web traffic. Understanding the specific functions of these ports can enhance your overall comprehension of networking and email transmission.
