RFC6152 - SMTP Service Extension for 8-bit MIME Transport
This memo defines an extension to the SMTP service whereby an SMTP content body consisting of text containing octets outside of the US-ASCII octet range (hex 00-7F) may be relayed using SMTP. [STANDARDS-TRACK]
RFC6409 - Message Submission for Mail
This memo splits message submission from message relay, allowing each service to operate according to its own rules (for security, policy, etc.), and specifies what actions are to be taken by a submission server.
Message relay is unaffected, and continues to use SMTP over port 25.
When conforming to this document, message submission uses the protocol specified here, normally over port 587.
This separation of function offers a number of benefits, including the ability to apply specific security or policy requirements. [STANDARDS-TRACK]
