What do you want to prevent from happening?
Mail that isn't specifically addressed "To" you not to get to you?
Look at the mail on this list:
To: users@spamassassin.apache.org
Subject: Re: Spam with my company domain
From: Jeremy Davila <jdav...@languageworks.com>
You realize, that would mean you wouldn't get this list mail, and
likely any other mail from any other list, right?

The information in the To: header has nothing to do with who actually
receives the message. Delivery is controlled by the "envelope To", which
is the "please send this message to" address communicated during message
transfer between mail programs.
There are more details available if you google "smtp envelope to address"
It's risky to use "my address isn't in the to:" as a spam sign, because
blind carbon copies would always hit and forwarded messages (e.g. from
your gmail account to your ISP account) would likely hit.
