Are you sure these are non-existant email addresses? In the past I
had an issue with an email user using this fancy feature called "spam
bouncer". It would send a fake bounce to the sender thinking they
would automatically remove his email from there list. I think Mail
Washer has this feature.

In the end with the help of users on this list I setup exim to refuse
to relay these fake bounces.
