SMTP Handshake

The SMTP handshake is the initial communication process between an email client and a mail server to establish a connection for sending mail.

The SMTP handshake involves a series of commands and responses between the sending server and the receiving server, including greeting, authentication, and recipient verification. A successful handshake confirms that the receiving server is ready to accept the message. This process is critical for deliverability because failures during the handshake can lead to immediate rejection or blacklisting.
