OTHER: How to get lots of false positives

If you LIKE getting false positives, here's how I did it:

1. Get a real spam.

2. Start a complaint letter.

3. Select and cut the full header of the spam to put in your complaint
   letter.

4. Briefly lapse into semi-consciousness, and paste the header into your
   blacklist instead.

To anyone who got a bounce and didn't get an apology, please take this one
(apology, that is).  It appears to be fixed.
