It also says that postfix is trying to make the connection; not sendmail 
as you suggested in your first email.  I have sendmail working on 
OpenBSD with static ip that does some domain hosting.  This machine is 
co-locate with no annoying ISP to get in the way either.  I once had my 
backup server at home to do hardware repairs and I could not get 
sendmail working (except inside box only) in the few hours I had to play 
with it.  I don't have any other experience with it.  I've never used 
postfix.
