SMTP, or Simple Mail Transfer Protocol, is a protocol used for sending and relaying email messages between servers. It facilitates the transmission of email from a sender's email client to the recipient's email server, ensuring that messages are properly routed and delivered. SMTP operates over the internet and is essential for the functioning of email services, allowing users to send and receive messages across different platforms.
An SMTP port is the port used to transfer email using the SMTP protocol. Typically SMTP is configured to use TCP port 25, although some servers will use TCP port 587.
