In theory true, you could run a TELNET listener on Port 25 or 135. But the world works a bit better when most people follow the same practice. Port 587 is for authenticated mail message submission.
I'm sorry, your last message seemed to indicate that you felt that Sendmail accepting unauthenticated mail on port 587 (if configured to accept unauthenticated mail at all) was not a problem; that, somehow, it was a *good* thing that it would happily apply the same policy to all ports it listened on, so long as one of those ports was 587. Is that not, in fact, your position? It is really hard for me to see encouraging people to run additional unauthenticated mail servers on some other port as a good idea, and it is really hard for me to read the actual text in your first message any other way than simply "mail accepted on port 587 good".
