Redirect the mail to user 'nobody' instead of trying to bounce it.  
/etc/mail/aliases redirects all mail for 'nobody' to /dev/null.

So your virtusertable entry would look like:

abc@xxxxxxxxxxxxxxx	nobody

Remember you need to put the full host in there as abc@xxxxxxxxxx gets 
"rewritten" to abc@xxxxxxxxxxxxxxx, then rewriting to the local username 
gets attempted.

Remember also to rebuild virtusertable:

makemap hash /etc/mail/virtusertable < /etc/mail/virtusertable
