OK...the out put of that command gave me:
sendmail 12817 root 3u IPv4 4777305 TCP
*:submission (LISTEN)
This is when I did what it looks like you're supposed
to do for the .mc file and activate this line:
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
I rebuild/restart sendmail and no other server will
talk to mine on port 25. The .mc file says it will
listen on both. Is there something else I'm supposed
to activate/deactivate?
Thanks!
Corey
