It's saying that sendmail is trying to open the network port for SMTP
and something else has it open already.  This smells like you're trying
to have two MTAs (mail transport agents) running.

After sendmail dies, do a "netstat -lpn" and look for a process that
has port 25 (SMTP) open.  If you do, then you already have an MTA
running (probably postfix) and you don't need sendmail.

Check "man alternatives" for how the system deals with postfix/sendmail.
