I hate spammers...

Just hit 4000 biunced messages for mail my host never sent. :-(

And got a bounce messages for legit traffic from the mailing list indicating that some the host is on a blacklist. Of course, they can't be bothered to list *what* blacklist.

So now I get to contact the admins, pardon me, *try* to contact the admins on those sites to find out what blacklist they are using and get the maintainers of said list to fix their mistake.
