Before you can configure Spam Assassin settings, you must have Spam Assassin Software installed on your server. Spam Assassin Software is $49.00 USD plus $50.00 CAD one-time Setup Fee. To request installation of Spam Assassin Software, please contact our Customer Representatives.

1. Login to Plesk Hosting Panel as administrator.

2. Under System, go to Server, then SpamAssassin.

3. To allow server wide filtering based on the settings you define, select the Server wide settings check box. To let your users set their own spam filtering preferences on a per-mailbox basis, select the Personal settings check box.

4. Now all the incoming mail will be filtered on the server side. By default, spam filter does not delete spam mail, it only adds the "X-Spam-Flag: YES" and "X-Spam-Status: Yes" headers to the message, and "*****SPAM*****" text string to the beginning of Subject line of each message recognized as spam.

If you have enabled the Personal settings option, then your users will be able to set their spam filters so as to automatically delete junk mail. They will also be able to set up their personal black and white lists of correspondents that will override the server settings, and teach the spam filter on a per-mailbox basis.

5. If you do not want your users to receive e-mail from specific domains or individual senders, add the respective entries to the spam filter's black list.

If you want to be sure that you and your users will not miss e-mail from specific senders, add their e-mail addresses or entire domains to the spam filter's white list.

To specify e-mail accounts for which mail should not be filtered, add the e-mail addresses of your users to the spam filter's ignore list.

6. Once finished with setting up SpamAssassin spam filter, click Up Level to return to the previous screen.
