Sure. You could even run an entirely separate copy of qmail processes
that interfaces with the same queue when you send out the newsletter.

You could probably alias anything that comes back to the MAILER-DAEMON
user during the time you are sending out the newsletter to be passed
through a program or script which would look at the ## line and see if
the subject matches the newsletter's subject, and, if it does, pass off
the user name to either a PHP function or otherwise marking the user as
bouncing in the database. As far as using PHP, you might do better with
a shell script; but my knowledge of PHP's speed limitations is
nonexistant.
