I recommend that no one use the CBL "anti spam but not for spammers" list.  It falsely accuses legitimate mail servers running on BSD of having windows trojans.  Clearly this is impossible.  They refuse to help or work with people they list. 

Further, if you do not get a reply from me make sure you or your ISP is not using that list. 

I hate spam as much as the next guy, but this is not the answer.  Worst of all, these people will not provide any evidence what so ever of the accusation.  There is no email with headers.  There is nothing they will give you.
