Teach the filter what is spam

On the Mail page of the console, use Mark spam on spam that was delivered and Not spam on wanted mail that was blocked. SpamDuster learns from every correction. Use Report phishing and Not phishing to record phishing detection mistakes.

How SpamDuster learns

SpamDuster learns from the corrections you make on the Mail page of the console. Each correction teaches the filter about mail like that message, so it gets more accurate for your mail over time. Corrections do not move or deliver anything on their own; the console tells you what each one does before you confirm.

Spam that reached a mailbox

  1. On the Mail page of the console, open the Accepted folder and find the message.
  2. Select Mark spam and confirm.

The filter learns to block mail like it. If it was phishing, select Report phishing as well.

Wanted mail that was blocked

  1. On the Mail page of the console, open the folder that holds the message, for example Spam.
  2. Select Not spam and confirm.

Not spam only teaches the filter; it does not deliver the message. To deliver it too, select Release + not spam. See Release a blocked message.

Phishing detection mistakes

Button Use it when What it does
Report phishing Phishing reached a mailbox or was filed as ordinary spam. Records the miss. Nothing is moved or delivered.
