Preventing Spam through Dspam in PLESK

From the Heyey! Butler with love:

Dspam is the new Spam Filter functionality built in PLESK. 
Open your PLESK control panel, and go to your desired mailname, click Mailbox and click on the checkbox next to “Enable spam filtering”. And then go to Spam Filter -> Training (the Spam Filter button will appear in the main mailname page).

To be effective you have to train Dspam with at least 10 spams and 10 hams (ham means non-spam email).

In the training section there’s an icon on the right of each mail:

- gray means the email was not scanned by Dspam
- green means it was scanned and identified as ham
- red means it was scanned and identified as spam

You just need to select the ones that are ham (and click “this is not spam”) and the same with spam.

If case of false positive after the initial training is done (i.e., a spam was identified as ham or a ham was identified as spam), you must come back to the training and select that particular mail and tell Dspam what it is. Remember, the more you train it, the more accurate it becomes and in the end it should never make a mistake as it’s very intelligent.

Also the black/white list feature in plesk works. You also put * in
there, ie:

*@spamdomain.com
vi@gra@*

The only feature that doesn’t work is the scoring in Plesk so please ignore that and concentrate on the scoring and whitelists and blacklists. Many thanks for your patience on this.
