Change anti-spam settings

PureMessage for Microsoft Exchange gives each email a spam rating. The higher the rating, the more likely the email is to be spam. PureMessage for Microsoft Exchange uses this rating to decide whether the email should be treated as spam. We recommend you set your ratings above 50 to avoid legitimate mail being classed as spam or suspected spam. You have the option to add the spam score as a Microsoft Spam Confidence Level (SCL) rating to the message.

Click Configuration > Transport (SMTP) scanning policy > Anti-spam, and then click Change anti-spam settings.

In the Anti-spam settings dialog box, use the slider controls to adjust the threshold above which PureMessage for Microsoft Exchange regards an email as spam or suspected spam.

Check the Check reputation of message relays against external DNS block lists checkbox. If you want to exclude certain relays from reputation checks, click Upstream trusted relay. See the Key concepts section for more information. Check the Check reputation of first external relay only checkbox after configuring the trusted relays correctly.

To add the spam score as a SCL rating, check the Add spam score to message as Microsoft Spam Confidence Level (SCL) rating checkbox. Message delivered to end users with a SCL rating higher than a particular value are diverted into the users Junk mail folder in Microsoft Outlook.

Note From the Manage changes menu, click Save changes to save your configuration.
