Praise or spam?

Had an email the other day, the sole content of which (in the subject line) was:

The best erotic story i ever read in my life

Which was nice - I'm just wondering which story it was, or if it's some bizarrely accurate spam.

But if you've read and enjoyed one of my stories, please let me know - and please let others know! Good reviews are for writers what fresh blood is for vampires - the power by which we will take over the world something which powers us and helps us to keep going.
