I previously posted this on comp.mail.sendmail and freebsd-questions.
After no answer and some extra testing, I believe this probably belongs
here.
--------
I need some help debugging a problem I am having with setting up Sendmail.
Previously, I have been using Exim, but I have decided to try my hand with
a different MTA. :)
Here is the error I just cannot seem to get around (with indenting):
Apr 21 16:10:14 gw sendmail[1985]: starting daemon (8.11.2):
SMTP+queueing@00:30:00
Apr 21 16:10:15 gw sendmail[1986]: f3LK0XL00702: SYSERR(root):
makeconnection: cannot bind socket [216.140.158.72]:
Invalid argument
Apr 21 16:10:15 gw sendmail[1986]: f3LK0XL00702: to<ME@blackhat.net>,

relaymail.blackhat.net. [216.140.158.10], dsn4.0.0,
stat=Deferred: Invalid argument
My setup consists of FreeBSD-4.2, Sendmail v8.11.2, a multi-home system
with a cable modem, analog modem, and a LAN.
I only wish it to receive on the LAN (192.168.1.0) and the analog modem
(216.140.158.72). This is easy to change (DAEMON_OPTIONS), but I just
can't get confCLIENT_OPTIONS to work. From looking at sendmail.cf, I can
see that it is being set:
# SMTP client options
O ClientPortOptions=Family=inet, Addr=216.140.158.72
Here are my files, interfaces, and routing tables. I have Exim working
with this, but I would like to get sendmail running. Also, I use IP
Filter to actually route the packets from the cable modem over to the
analog modem, but this is not the problem.

I am now using FreeBSD-4.3 with Sendmail v8.11.3 without any change. I
even wrote a little program to see if everything was going alright. With
my test program I am able to bind a random port with a problem. It just
appears Sendmail does not want to.
Using GDB I compared the two sockaddr_in structures in my program and
Sendmail (daemon.c:2095). The values were exactly the same.
I just don't see why this bind would fail on the PPP device and not the
ethernet cards. Hopefully, this problem is user-oversight and someone
sees what it is. <hint, hint>. :)
TIA,
Sean
