if you start denying then the attglobal.net server will generate
bounces, most of which will be collateral spam, as the sender address
will be probably forged. Either you abandon the forwarding service
and address and deal with your mail yourself, or you should not deny
messages that have been forwarded. The only exception is denying
based on unroutable sender address, as this should by definition not
generate deliverable bounces (you can even do sender callouts if you
like).
