I wonder how long it will take before people start finding them out and
beating the crap out of them. God rot their bones.

Friday, as I was (unsuccessfully) trying to scan my public IP for open
ports, I scanned yours as well:
Port State Service
21/tcp open ftp
22/tcp open ssh
80/tcp open http
111/tcp open sunrpc
179/tcp filtered bgp
443/tcp open https
512/tcp open exec
515/tcp open printer
648/tcp open unknown
3306/tcp open mysql
6000/tcp open X11
Here at least there was no SMTP port open, but the only IP I scanned was
the one bound to your domain. Could some other machines be running
sendmail as well? The firewall seems not to have been running at the time.
I just scanned you again and got the same result.
Sorry I can't help on sendmail - this is a complete mystery to me. Had a
look at sendmail.cf the other day and suffered a heavy headache right
away. Reminds of the old newbie days as configuration files made no sense
except perhaps somebody pulling my leg.
Cheers
