So may the source be with you.
Go ahead, take the source, write the "anti loop checking code" and
commit it to the developers ...

But be aware: a simple "if($fwd_email == $USER@$DOMAIN)" will not be
enough. $fwd_email could be "[EMAIL PROTECTED]", which is an
alias to "[EMAIL PROTECTED]" which forwards to
current user ...

Maybe _it is_ easier to write a message and push this into all ~30k
postmaster mailboxes, telling them to _not_ create mail loops????
Best regards
