Global Default Domain Anti-Spam Settings
Unless a domain or individual user account has selected to override the default settings, these Anti-Spam settings will be applied to all Domains and User accounts on the system. See the sections below to modify individual Domain or User account settings as well.
To configure the global default domain Anti-Spam settings, follow the instructions below.

Check the box next to "Incoming Weight Threshold" and set it to 60.
Click Save.
Domain Anti-Spam Administration
If you are logged into SmarterMail as Admin and you want to modify an individual Domain's Anti-Spam settings, Click on the Manage icon at the top and Click All Domains.
Right Click on the Domain you wish to edit, and go to Settings > Spam Filtering
Under the Options tab, you can either set the domain to use the Global Domain Anti-Spam Defaults (Use default spam settings), or you can override the defaults and customize the rules (Override spam settings for this domain).
If you want to customize the domain's Spam settings, select the "Override spam settings for this domain" option and Click Save.
Click on the Actions tab.
Here you can modify the Weights that are applied for each spam check, however, we recommend you leave the Weight settings at their default values.
The easiest thing to modify is the Probability of Being Spam settings below the Current Weights section.
The default values are to mark the email message's subject with "SPAM-LOW", "SPAM-MED", and "SPAM-HIGH" depending on the Weight of the email message. The more spam filters the email message triggers, the higher the Weight of the message will be, which in turn decides which action to take on the message.
You can change the Weights and Actions of each of the Probability sections to meet your needs.
We recommend the following settings.
Low Probability of Being Spam:
Weight: 10
Action: Add Text to Subject (SPAM-LOW: )
Medium Probability of Being Spam:
Weight: 20
Action: Add Text to Subject (SPAM-MED: )
High Probability of Being Spam:
Weight: 30
Action: Move to Junk E-Mail folder
User Spam Filtering Settings
When logged in as an individual user's account, Click on the "Settings" icon at the top, Expand the "My Settings" folder on the left, Expand the "Filtering" folder and Click on "Spam Filtering".
To override the domain's default spam settings, choose the "Override spam settings for this account" option and Click Save.
Click on the "Actions" tab.
You may now adjust the Low/Medium/High Probability of Being Spam Actions to best fit your needs. The only thing end-users can change for their Anti-Spam settings is the Action to take on different predefined probabilities of Spam. To change the actual settings the Spam Filters use to determine the level of probable Spam, you must be either a Domain Administrator or SmarterMail Admin.
