If it is any consolation, I am a dedicated SA user on my personal server and our list management product (Lyris) uses SA as a tool for helping us understand the "spaminess" of our correspondence.
I remember emailing Lyris to recommend that they do that. I get the Neat Net Tricks newsletter (http://neatnettricks.com/) which uses Lyris and it was getting caught by SA. Good to hear they listened to me! ;)
