Yeah, but have you ever seen an e-mail that uses "tit" as a reference to a small bird (except in this list
:-) )?

But seriously, you're right about the word breaks. Without them you're gonna reject a whole lota e-mail
erroniously. Spammers are getting creative too. I'm receiving e-mails where the subjet line contains for
example, not the word "sex" but "s.e.x.". That gets it through my filter. How do you handle that one?
