	Hmm.  Actually, I think you may be on the right track, but not 
with regards to load average.  The more recent versions of sendmail 
will also allow only so many simultaneous connections open, and that 
can also be a bottleneck.  Proper tuning of SMTP_MAX_RCPTS is 
definitely something you want to look at -- too large can hurt you, 
as can too small.
