i used to be a sys admin for a company that was just like your third-party
service... we had about a hundred servers (win2k, linux, sun, etc) on a
30Mb fiber pipe... we would routinely move 200 million messages per month...

for one machine, that's respectable... your real world performance will
undoubtedly be lower (the mailing machine needs to be able to accept bounce
notifications, subscribe and unsubscribe reqs, etc)...
you will never get 6 million sends with one machine... think about running
a cluster (ie: one machine composes messages and passes them off to mailer
slaves)... there's a lot of ways to skin this cat...

we're working, right now, on a clustering technique... using the best of
qmail, mysql and a homemade beowoulf clone
some things to think about, anyway...
