This question would be better on the Exchange list... Blocking the domain doesn't resolve the underlying issue. Why are those messages there?
Either you aren't doing recipient filtering, so they are bounces for unknown users, or your server is being abused. Therefore rather than trying to deal with the symptom, deal with the underlying cause. Recipient filtering should be enabled, which will mean your server drops messages for non-valid recipients at the point of delivery. http://www.amset.info/exchange/filter-unknown.asp If you have recipient filtering enabled, then check that your server hasn't been compromised and is being used for authenticated relaying or an open relay.
