One type of mail that I am constantly getting incorrectly classified as SPAM is when I do business or ask for a password from a site.
I wonder if SA's accuracy re: false positives might be improved if I could have it process my "Sent" folder to look for people I've sent email to recently.
Ideally, it'd be a time-decay type list, with the ability to blacklist a company if it became abusive...
Just a thought on reducing false-positives of a type I frequently get....
