Mainly, a false positive is due to:
- javascript embedded in the mail, e.g. web developers.
- spam text in the mail, e.g. anti-spam people ;)
- "anti-spammed" From addresses, e.g. the from address as a result has
no valid MX. Happens with mails gatewayed from USENET.
- and users who's ISP has been listed on the RBL.
What I generally do is refile the spam into a folder, so I can check it
once every now and again for false positives (and see how much spam I get
nowadays). I don't recommend bit-bucketing it without running it past a
human first...
