I'm running a server - not a client. On the server I need to be able to both send and receive mail using SMTP on port 25 to/from other servers. I'm not catering for POP mail on port 110.
Homer,
I've lost track of what's going on here. What is your current status and problem? Are you sure it's not a network issue (firewall, router, ISP blocking the port, etc.)? Try also taking a look at the "Sendmail SMTP AUTH HOWTO" on my website [1]. While the concept is not exactly what you want, the steps shown for enabling receive from the network should work for you.

Only note that the sendmail.mc included there shows this line:
* define(`confAUTH_OPTIONS', `A')dnl
In reality, the Fedora installation of Sendmail has `A p' instead. Remember to remove the "p" or else it won't work; this is an error which I have regrettably not fixed yet in the document.
Cheers,
