What does the acronym “SMTP” stand for in the context of email communication?

SMTP stands for Simple Mail Transfer Protocol. It’s the standard way email servers send messages to each other. When you send email, SMTP delivers it to the recipient’s server.

SMTP isn’t primarily about security or text formatting. It focuses on transferring mail between servers. Other protocols handle encryption and security.

Every email you send uses SMTP behind the scenes. It’s been the email delivery standard for decades.
