Google Apps - Blocking a sender with Gmail

This is a quick set of instruction for where to locate the configuration for adding a domain (or user) to the blocked list for your domain when using Google Mail as your mail provider.

Access the Admin console

Select Google Apps

Select Gmail

Select User Settings

Select Blocked senders in the Spam section of User settings. This is where you will add the domain or user to block from sending to your Google Mail domain. 

You need to add a new list (I used the name of the domain I wanted to block) and then add the domain to this list. 

Select Edit on the new list created and add the domain you wish to block. 

The newly added domain will be blocked once you select Save (from the configuration) and Save Changes (in User Settings).
