When David and I worked at Student.Com, we managed a large opt-in
mailing list. We set up a system where we'd record bounces in a
database, and if you bounced 3 weeks in a row, we'd unsubscribe
you. That allowed us to filter out noise from legitimate bounces.

We also incorporated a tracking code in the body of every message, so
if someone replied with an "unsubscribe" request from a "from" address
other than the original "to", we could properly handle the request. We
found that lots of times people had accounts set up where there wasn't
a direct match -- which made it hard to automate without the code.
