This snags when the gateway is running something like Sendmail.  I believe
that one mail destined for 800 recipients will end up on the gateway as a
single queue entry with 800 destinations, and these are still processed
single file, in order.  If one hangs on a connection for one minute, every
address behind it is also held up for the additional minute.  Thus you
still have the problem, only to a lesser extent because the baseline
delivery will be faster due to the larger data pipe.

I hate hype, but I'll mention it yet again: TLB can deliver straight to
your gateway without going through a mailer on your local machine.  I
suspect that the program that originally started this thread could do the
same, given probably a small bit of code tweaking.
