Managing your Allow / Block Lists


Managing the allow and block lists in the console is essential to ensure that users are not opening up security holes in the system when they're adding people to either list. If you see an email gets through the system that seems like obvious spam, it is usually because the user has added it to their allow list.

This article is going to cover:

  • How to navigate to the allow and block lists for domains and users
  • How allow and block lists function within Mailprotector
  • How to add and remove addresses or domains to the allow and block lists

How to navigate to the allow and block lists for domains and users:

As a manager, there are multiple levels that you can manage. The Reseller level, Customer level, Domain level, Group level, and User level all have their own allow and block lists. The higher you have an allow or block rule in the hierarchy, the broader scope of users it will apply to. Getting to the allow and block rules is the same regardless of which level you want to manage.

  1. Navigate to the Mailprotector console at
  2. Go to the desired level you'd like to manage (Reseller, customer, domain, group, or individual user)
  3. Select the "Filtering" tab 
  4. Select "View" next to either the Block or Allow rules section

How allow and block lists function within Mailprotector

There are a few rules that remain consistent between the allow and block rules in the Mailprotector console.

Those rules are:

  1. Allow rules will always supersede block rules. This means that if there is a block rule for the domain "," but there is an allow rule for "," Mailprotector will allow email through for and block email from any other address at
  2. The Block and Allow rule fields are exact match fields. This means you cannot use wild cards or generalized addresses like "example." You must put a domain or email address in.
  3. If you've put in "" as a block rule, Mailprotector will not block subdomains such as "" You will need to add the subdomains individually or create a Message Rule.
  4. You can copy and paste multiple addresses to add to the allow or block rules fields. If multiple values are added, there will need to be a space or line break between the values.mceclip0.png
  5. To remove a block or allow rule, you need to select the "View" button just below the rule count. This will bring you into the list of current rules. From here, you can choose the rule you want to remove and then select the trash can icon.mceclip1.png
