I'm not sure what you mean. But, if all the port is active, sendmail works f
or every port.

In my case, sendmail 8.9.1 is working on SE/30. It has 2 active ports. One i
s for ppp connected with ISP and another is the Ethernet. The SE/30 can reci
eve e-mails from both ports. And also e-mails from the inside(Ethernet) can
transit the SE/30  and have a direct SMTP link with outside machines.
