interfaceaddress
, port
)
SMTP over TCP/IP channels normally connect to the remote system's port
25 when sending messages. The port
keyword may be used to
instruct an SMTP over TCP/IP channel to connect to a non-standard port.
The interfaceaddress
keyword controls the address to which
a TCP/IP channel binds as the source address for outbound connections;
that is, on a system with multiple interface addresses this keyword
controls which address will be used as the source IP address when PMDF
sends outgoing SMTP messages. Note that it complements the Dispatcher
option INTERFACE_ADDRESS, Section 11.3.2, which controls which interface
address a TCP/IP channel listens on for accepting incoming connections
and messages.
