The problem seems to be sendmail itself. Here's what I've done to isolate the
problem.
1) changed /etc/rc.conf to NOT start sendmail or anything mail related
-- sendmail (external stuff, the local daemon still starts in
/etc/defaults/rc.conf)
-- dovecot
-- saslauthd
I know that saslauthd isn't exactly mail related but I installed it for
sendmail
2) rebooted the computer (and verified that it did actually reboot by using
uptime). I'm not sitting in front of this computer, I'm "ssh-ing" into it.
3) once restarted, I wrote a little C program to open a socket and then bind
the ip address 192.168.2.23 (the machines IP) and port 25 to that socket.
The effectiveness of this program was verified using sockstat. If necessary,
I will post the source code, but didn't see much need to now. The program
worked and the bind(2) call made no complaints.
4) Stopped ALL sendmail processes (/etc/rc.d/sendmail stop)
5) edited /etc/rc.conf and re-enabled the "external" sendmail process
6) Started sendmail and now see the exact same problems in /var/log/maillog:

What does one do when sendmail is it's own worst enemy?
Any help is greatly appreciated because I don't understand at all what I could
have done to this. If necessary, I'll post my <hostname>.mc file for all to
read. Heck, I'll post whatever is necessary because this has to be working.
