I have the problem that I get Delivery Failure notice and such mails sent to
one email address. This also includes Vacations Answeres an such stuff.

Theese answeres are sent on Spam - so someone is faking the "From:"

Reading the subject tells that is definitivly spam.

Is there a possibility to catch this?

It's about 20 mails per houre...
