SMTP AUTH

SMTP AUTH (Simple Mail Transfer Protocol Authentication) is a security feature that verifies your identity when sending emails through a mail server. Instead of allowing anyone to send emails using the server, SMTP AUTH requires you to log in with a username and password. This process helps prevent unauthorized users from sending spam or malicious emails. Essentially, it ensures that only legitimate users can send emails through the server, adding a layer of security and helping maintain the integrity of email communication.
