Weird.

Just looked at this machine (RH7.0 upgraded to 7.1, sendmail installed
as an afterthought) and it's the same. I'll solve it on this box and let
you know.

// looks...

Okay, it's not as bad as I thought.

Line 259 of /etc/sendmail.cf, reading:

O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

Change the Addr value from 127.0.0.1 to 0.0.0.0 - INADDR_ANY in sockets
terms, and it'll listen on all ports.

Looking up how to make it listen on two specific addresses I'd have to
actually look up.

Dave.
