Set up a server-side bayesian filter to block all e-mails containing certain words (such as 'address not found' or similar). I'd be very suprised if there isn't a filter like this already available if you google it. Have a look at the 'fighting useless notification mails' thread from a few days ago, which is a related topicWhat do you all suggest to this 'seemingly' DDOS-attack (allthough not intended as a DOS)?
This would be an option if the mailserver is still capable of handling all or some of the mail. As the question was raised, this is not the case. The 'theoratical' situation is that my mailserver is as dead as a doornail (not really crashed but out of oxygen..network-bandwidth).
Thanks anyway for the response (and yes, the thread on fighting.... is indeed very helpful for the case where I have some 'spare' bandwidth)
