Send it in 2 postings, that's easy enough.

If you have a million addresses, and half bounce, you *will* get into everybody's
spam filters, because it will look like a "dictionary attack".

Also, if your data is *that* crufty, you almost certainly didn't get a verified
opt-in from the addresses, which will make you very suspect in many people's eyes.
(Listserv's "Subscribe = ,confirm" meets any sane definition of verified opt-in).

If more than 1% is bouncing, you have problems.  Big ones. Even 1% is 10K
bounces for a million-address list.  And you should only be seeing 1% bounces
on a list that's getting infrequent (monthly or so) postings, simply because 1%
of the people will get new e-mail addresses each month or so.  And if you're
posting to the list weekly and washing your list, you should be well under 1K
bounces/posting.

Your hardware is almost certainly up to the task.  The only way a Windows box
will suffice is if you're running LSMTP.
