	I'll respond to the list, because I feel very strongly about this subject.

	IMO, cisco does nothing but seriously screw up the SMTP protocol. 
Under no circumstances whatsoever should you use anything from them 
that comes anywhere close to touching the SMTP protocol.


	Now, if you want to talk privately about what it takes to set up 
a "high volume mail project", I'll be glad to do so.

	However, I will also first recommend that you read the slides 
related to this subject that I have at 
<http://www.shub-internet.org/brad/papers/sendmail-tuning/> and 
<http://www.shub-internet.org/brad/papers/dihses/>.  These are from 
invited talks that I did at SANE'98 AND LISA 2000.

	You may also be interested in the paper from Nick Christenson at 
<http://www.jetcafe.org/~npc/doc/performance_tuning.pdf>, and if you 
can afford to wait until the 20th of September, you could buy his 
book _Sendmail Performance Tuning_, ISBN 0321115708.


	Disclaimer: Nick was my co-author for my invited talk at LISA 
2000, and I was a technical reviewer for his book.
