Configuring SpamAssassin in Plesk

tech bench 2A few week’s ago in the Tech Bench, our Director of Network Compliance, Mike Witty, discussed some of the finer points of preventing your important emails from ending up in your clients’ spam folders. Next, we looked at how to configure SpamAssassin in cPanel.

This week, it’s time to turn our attention to configuring SpamAssassin in Plesk.

ServInt VPS accounts using the Plesk control panel come with SpamAssassin as part of the standard installation. The default configuration has SpamAssassin enabled.

If you need to reenable SpamAssassin:

-     In Plesk, click Tools and Settings on the left-hand navigation bar.
–     In the Mail group, click “Spam Filter Settings.”
–     Select the check box for “Switch on server-wide SpamAssassin spam filtering.”

As the name suggests, this will enable SpamAssassin for all email on the server.

This basic setting will filter all of your email for spam.  It will not, however, force your users to do anything with it after it’s filtered. It will simply mark spam as spam, nothing more.

Configuring your internal SpamAssassin score threshold:

If you see too much spam getting by your filters, you can lock them down further by adjusting your internal SpamAssassin score. From the same “Spam Filter Settings” window in Plesk, adjust the variable in the “The score that a message must receive to qualify as spam” box. Lowering the number will make your filters more selective.

Note: It is important to note that making any of these changes will affect all email accounts on the entire server. You should therefore make sure all your clients are aware of the settings you are changing.
