IMPORTANT!!! Possible open relay bug in Zmailer!!

I have been alerted to what I think is a bug that leaves pretty much any
zmailer config open to relay... Has anyone else encountered this?

If I have a box called mail.test.com

And I have a session with it like this (forgive the syntax.. outlook
likes to play with my typing):

Helo
Mail from:whoever@wherever.com
Rcpt to:some_guy_who_should_never_get_this_message%aol.com@mail.test.com
Data
Yadaydyadyadya
Dyayd
Ayd
Ayd
Yad
.

The problem is: some_guy_who_should_never_get_this_message@aol.com
actually receives the message!!!!!

How can we prevent this? PLEASE HELP!!!
