Sendmail, when doing direct delivery( the default) attempts to send 
the message onto the next hop before it closes the session.  There 
are various reasons we're using sendmail the least of which is that 
our chief programmer insists.  If we can make it work with something 
else ( qmail and postfix didn't work) then great.  Right now we use 
sendmail on deferred delivery (queues everything) and sort the queue 
every five minutes using various headers and the destination domain 
as criteria.
