When you want to do mass-mailing, the best thing to do is see how the
Big Guys do it right. No, not the spammers, since they do it all wrong.
It's the mailing list management software we need to look at. I do not
know how others do it, but with Mailman:
- the "To" header does not necessarily have to be munged, it can be
[EMAIL PROTECTED] or whatever policy dictates,
- the email is sent with a different envelope sender address. With
Postfix's /usr/sbin/sendmail compatibility wrapper you do this
using the '-f sender' parameter (see manual page for more
details). Mailman sets this to [EMAIL PROTECTED]
- the Errors-To header is further defined, with the same
[EMAIL PROTECTED] address.
What happens is that email comes from whatever is defined in the "To"
header, but the Return-Path, Sender and Errors-To headers all point to
the admin address, and that's where any decent mailer-daemon should send
bounce-back reports.

If you're willing to learn Python, you may actually want to look at the
source code of Mailman. AFAIK it's fairly MTA-neutral, and Python's
support for database backends is pretty good and easy enough to learn
and use. Of course you can use any other scripting language, as well. :)
