My first thought was: Clean some of your crap out of your mail folder! Temporarily, at the very least, to stop the bounces. Personally, I think a hard bounce is more courteous to the senders. Sure, it'll mess up list subscriptions, but that's what you get for not keeping tabs on your quota. But a bounce will alert the sender so they can follow up with a reliable method of communication. I know people will get their knickers in a wad over this, but I don't think that anyone should rely on email for anything of real import. 2010 or not, it's not (obviously) very reliable in that you'll never know if the recipient actually read it. Fax it, call them, send a letter. I worked support for an email provider for a while, and I regularly shook my head in awe of the epic stupidity (ignorance, if you prefer) of people trusting such an ethereal medium for "important" correspondence.
