The bogus and mybogus files have nothing to do with anything about any mailbox server, virtuals, etc. Any IP that will be sending MAIL FROM: @sender.domain in either of those files must have matching A + PTR records (which hostname themselves have nothing to do with the @sender.domain) if an IP has: D.C.B.A.in-addr.arpa PTR joe.blow then domain joe.blow A A.B.C.D Len
