No such user This is a case where trying to be anonymous works against you. There are a couple of forwarding services (iname.com is one) that seem to be having a lot of this trouble lately. If we could see the real domain involved it might help diagnosis. But yes, it is a bad mail server somewhere else that is mangling the address in the error report. Set Auto-Delete= No in the List Header and process the errors manually for a day or 2 and you will see.
