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: see below Jan 4 17:36:42 whitbap sm-mta[975]: starting daemon (8.13.8): SMTP+queueing@00:30:00 Jan 4 17:36:42 whitbap sm-mta[975]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Jan 4 17:36:42 whitbap sm-mta[975]: daemon MTA: problem creating SMTP socket Jan 4 17:36:42 whitbap sm-msp-queue[979]: starting daemon (8.13.8): queueing@00:30:00 Jan 4 17:36:42 whitbap sm-mta[978]: m010sNBM004564: to=<jqyuehutmqluz@epilot.com>, delay=3+23:42:19, xdelay=00:00:00, mailer=esmtp, pri=2555114, relay=mail02.interchangeusa.com.

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. Andy
