Prevent SPAM with a Subject: spell checker?

Seems to me a logical (though I realize significant overhead) solution to most spam is to "spell check" the subject line. In a cursory review of over 1000 spams to my account, I've noticed over half use "misspelling" to get around filters. I don't mind if a message is rejected and notifies the sender they need to learn how to spell. More than likely, if it is a valid email, the sender will correct and resend.

DOES ANYONE KNOW OF A PRODUCT THAT DOES THIS AT THE SERVER?

I'm using Postfix and am quite happy with it so whatever I'm looking for must interface with it.

THANK YOU IN ADVANCE!:confused:

Not even just mispelling, they also use 1337 to get by it :)

See? No spellchecker would get that, just put in all sorts of 1337 words into your filters and whatnot and it should stop it.

to get 1337 words there are like 50 l337 converters you can get and put in words you see alot in these.
