Sorry, that's what I meant. I was editing the .mc files.
> Make sure there is no sendmail listening (port 25 or 587).
Here's what I did:
1. Killed all sendmail processes
# killall -9 sendmail
#
2. Wiped out all custom sendmail config files and created fresh clean
standard ones.
# rm hostname.*
# make all
2. Listed everything before starting up sendmail
# netstat -naf inet
Active Internet connections (including servers)

I don't see anything that should conflict. Do you?
3. Started sendmail
