	There are a lot more variables here.  For example, how many 
messages are going to be sent to these lists per day?  How large are 
those messages going to be?  How many of those recipients are going 
to be on the same recipient servers?  How fast do you need to deliver 
those messages?

	I would suggest searching through the FAQ for the word 
"performance", and reading all the entries that are returned.  Also 
search for "VERP".  After you've done this, if there's anything in 
section 6 that you haven't already read, then read it now.
