blocking %00 / %01 exploits with mailscanner?

[Dan Hollis]

Is there a way to get mailscanner to block %00 / %01 uri exploits in the
body of mails the same way mailscanner can block iframe exploits in the body?

I want to drop these mails into /dev/null hard, i'd like mailscanner to do
it, not procmail.
