The purpose of SMTP authentication is to verify that the sender of an email is authorized to use the SMTP server, helping to prevent unauthorized access and reduce email spam.
SMTP authentication is used for verifying the identity of the sender before allowing the email to be sent through the SMTP server. This helps ensure that only authorized users can send emails.
The purpose of using SMTP (Simple Mail Transfer Protocol) is to send emails from a client to a mail server or between mail servers. SMTP handles the routing and delivery of emails.
The authentication command for SMTP is “AUTH.” This command initiates the authentication process, requiring the sender to provide valid credentials.
SMTP relay authentication is required to prevent unauthorized users from sending emails through the SMTP server. It ensures that only authenticated users can relay messages, reducing the risk of spam and abuse.
