The information in this article applies to:
The Microsoft Mail Gateway to SMTP always connects to the designated SMTP host to send out messages. The gateway receives messages from any host that can connect to the gateway. When using TCP as the transport mechanism, a TCP connection is made by the sender to the receiver's service port 25. When the Microsoft Mail gateway has mail to send to the SMTP world, it initiates a connection to the designated SMTP host's service port 25.
