Blocking an entire Top Level Domain

This article will guide you through the process of adding a custom Content & Policy rule which will quarantine any messages from a particular TLD, such as .US or .Org.  Mailprotector recommends only taking this action if you are absolutely sure you do not need to receive mail from the top level domain you are blocking, as this will quarantine any messages from that TLD, regardless of spam score.

Please note that in this example we are creating a Domain level rule, which will apply to all users.  You can follow the same directions on the User Group or User levels, if you wish this rule to only apply to some users.

 

Creating a Custom Content & Policy Rule

To create a new Content & Policy rule, select "Content & Policy" from the right hand menu.

Click on the "Add Inbound" button to begin constructing a new inbound rule.

 

Construct your new rule as shown, substituting ".us" for whichever TLD you wish to block.

Configuring Your Rule to Block a TLD

 

Construct your new rule as shown, substituting ".us" for whichever TLD you wish to block.

 

Note: You can repeat this step to list multiple TLDs

 

Once you have the TLD(s) you wish to block listed, configure your rule to sent messages to either the spam or policy quarantine.

Mailprotector recommends sending to the policy quarantine when constructing a custom rule.  This makes it obvious that the message was quarantined due to a policy rule.  As well, you can prevent your users from releasing messages from the policy quarantine, if you so choose.

 

Once you are satisfied with your rule, click the button.

 

 

 

Temporarily Enabling or Disabling a Rule

 

Newly created rules will default to being active, however, you can disable a rule at any time, without needing to delete it, by simply turning it off from the Content & Policy page.

A rule that is turned off will not take any action on a message.  A rule can be turned on or off by clicking on the On / Off slider in the "Status" column.
