Sendmail on two IP's?

Basically, here's my setup.  I've got a 386 which I use as
a router between my class C network and a perpetual PPP link
to my ISP.  For some reason, sendmail refuses to run in daemon mode on this machine.  I've tried two different versions of sendmail, each time it puts this in the syslog:

Dec 22 19:09:59 giraffe sendmail[52]: NOQUEUE: SYSERR(root): opendaemonsocket: cannot bind: Address already in use
Dec 22 19:09:59 giraffe sendmail[52]: problem creating SMTP socket

Anyone know what's going on, and how I can fix it?

Do you already *have* sendmail running on this
machine?  The "cannot bind: Address already in
use" leads me to believe there's a program
already bound to the SMTP, or e-mail port (25)..

I fiddled around a little and got a similar error
message when I tried to start up sendmail a
second time.  Basically, it seems something's
blocking sendmail from connecting to that port.
Try running "netstat -a | more" and look for
something bound to the smtp port.
