You can't prove something that isn't true.

tcpserver doesn't care about the IP address of the sender, if by "the IP
address of the sender" you mean the IP address from which the sender originally
sent the message. It cares only about the IP address of the remote host that's
connecting to you to deliver you the message. If that remote host is
209.244.137.13 and you have "209.244.137.13:deny" in your rules file and you
have everything set up correctly, then you will not receive mail via SMTP
directly from 209.244.137.13, period. You may receive mail from that host if it
was relayed through some other host from which you accept mail, but that has
nothing to do with things being disguised as bounces or anything "slipping by"
tcpserver.
