I use Perl and sendmail to send out a weekly newsletter to about 10,000 e-mail addresses. Don't worry - the newsletter is completely legitimate, and everyone has signed up with a double-opt-in.

Every week about 500 (5%) of those e-mail addresses bounce back.

Is there any way, using sendmail, qmail or any other module, that I can automatically unsubscribe e-mail addresses that bounce?

Currently, whenever an e-mail bounces, I manually (and tediously) go into the database of e-mail addresses and delete the entry.

Thanks so much!
