Sendmail failes without daemon running

[Scott Wells <scott_(_at_)_shadowsystems_(_dot_)_tzo_(_dot_)_com>]

I am having a problem sending mail one of my machines.  The machine does 
not run a sendmail daemon.  I send mail, and get watch ps -ax, and see this:

13096 p0  I       0:00.03 send-mail: ./g711gZng013096 localhost: user 
open (sendmail)

Which makes me believe that it's trying to connect to a local MTA, 
however, there's not one running.  I've already read through the FAQ and 
mailing lists, and saw a couple of threads that appeared to deal mostly 
with misconfigurations and relaying.  However, I'd made no configuration 
changes whatsoever.  I've checked /etc/hosts, and it's fine.  Any other 
suggestions?

I'm running 3.1 with all patches applied.  Here's a the maillog entries 
for the above mentioned attempt to mail.  I think what I need to to is 
figure out how to make it use another system as an MTA, but not sure 
how.  I'm running the exact same configuration on 2.9, and it's working 
normally.
