How to set up MSA, port 587 on Postfix server. RFC 2476...
A mail submission agent or MSA is a computer program or software agent which receives electronic mail messages from a mail user agent (MUA) and contacts an mail transfer agent (MTA) for delivery of the mail.
Many MTAs act as an MSA as well, but there are also programs that are specially designed as MSAs without full MTA functionality.
RFC2476 recommended port for MSA is 587.
Separate names with a comma.
