I'm not sure if I understand your problem correctly, but what you did with 
these defines is that sendmail contacts every other system at port 2525 
insetad of 25, it's not listening on 2525, hence you can't see a tcp/2525 
with netstat -a.

But I think it should do what you want, if I understand your description 
right. If you want sendmail to listen at a custom port these defines are 
wrong. I don't have them in my mind right now, I'm sure you'll find the M4 
defines at the sendmail FAQ, tell me if I can help.
