Version 2.0 - July 5, 2006 Add Grey-Listing, two new quarantine features, and major upgrade of SpamAssassin...

  1. Three new features, all based on individual SpamBuster preferences:
    • Grey-Listing will reject all incoming "new" mail, then accept it if resent within normal resend limits. Most spammers do not bother to check for (or resend) rejected mail. (The operation of grey-listing is actually more complex and subtle.) This is an opt-in feature.
    • Auto-discard limits the amount of mail that accumulates in the Spam Quarantine.
    • Mass-discard - a convenient way to discard all messages in your quarantine (based on age or score).
  2. Detection engine upgraded from SA 3.0.4 to 3.1.3 (a major upgrade)
  3. SpamBuster terminology change from "hits" to "score" (most noticable in the spam tags added to the message headers).
  4. SpamBuster statistics - by the month, day, and hour. Also, the top sources (and receives) of spam. Archives going back to January 2004.
  5. All traffic distributed locally via CSE mailing lists is now filtered by SpamBuster, based on individual recipient's SpamBuster preferences.
