To block a domain:

1. Click the “Administration” tab
2. Click the “Accounts” sub tab. If you have multiple accounts, click an account link to open the Account Summary page for the appropriate account.
3. Under the Account General Information panel, click the “Submit Domains” link in the Blocked Domains field.







4. In the “Enter Domain Addresses to Block” field, type the domain that you want to block. Each domain must be on a separate line (press the Enter key to start a new line). You can enter up to 250 domains to block.
5. Refer to the How Blocked is Applied box for formatting rules when entering domains.
6. There are two counters in the top-right corner of the field to help you keep track of your total number of blocked domains. One counter shows you how many domains you currently have blocked for the account, and the other shows you how many you have remaining that you can submit to be blocked.
7. Click “Submit” to save the blocked domains.
