Gmail does it. Emails from mailing lists often have a header that specifies an email address you can email to unsubscribe (you just need to send an empty email to the address). Gmail detects this header and asks you if you want to unsubscribe instead of marking as spam. If you do, it sends the unsubscribe email for you.
