I've added it, but I get the same problems. As noted in my previous post
I've now found I can access the port from the postfix machine, just not
other machines.
Use netstat or lsof to see if postfix is really listening on
the external interfaces.
If postfix doesn't appear to be listening on the external
interfaces, check your master.cf. Some distributions of
postfix change master.cf to force postfix to listen on
localhost only.
Look for a line in master.cf beginning like:
127.0.0.1:smtp inet ...
and remove the "127.0.0.1:" part.
If this fixes the problem, complain to your distributor.
If postfix does appear to be listening on external interfaces,
then you have firewall software on that host interfering with
postfix.
