A little while ago I received the first genuinely useful piece of spam at a catch all address for one of my sites. I reproduce it here for posterity:

Recipe for great BBQ Sauce:

1 quart apple cider vinegar 
1 (20 ounce) bottle ketchup 
1/4 cup paprika 
1 pound dark brown sugar 
1/4 cup salt 
1 tablespoon black pepper 
2 tablespoons red pepper flakes

1/2 cup lemon juice 

DIRECTIONS
In a large container, mix together the apple cider vinegar, ketchup, 
paprika, brown sugar, salt, pepper, red pepper flakes, garlic powder, 
Worcestershire sauce and lemon juice. Pour into an empty vinegar bottle, 
ketchup bottle or other container and store in the refrigerator for up to 
1 month.

Wonderful. I can't wait to try it out!

I'm sure the spam was just an attempt to find a valid email address by using an innocuous payload. It also looks like I'm not the only one to get this
