Simple Mail Transfer Protocols (SMTP) commands, control and manage the sending of emails by using a set of protocols which are instructions and rules that facilitate the emails transfer across networks.
Most SMTP implementations support at least the basic set of SMTP commands defined in RFC 5321 — like HELO/EHLO, MAIL FROM, RCPT TO, DATA, RSET, VRFY, NOOP, and QUIT. These are enough for standard mail delivery and are almost universally supported. If you’re curious about extended commands (like AUTH, STARTTLS, etc.), they depend on the server’s configuration and what extensions are advertised in response to EHLO. WarmupSMTP Company
