Blacklist a domain
Mandrill allows you to add email addresses to your Rejection Blacklist manually. You cannot add an entire domain. However, you can set up a rule to reject any emails that Freedom attempts to send to based on a particular domain. For example, if you are sending test emails to a domain that doesn't exist or attempting to block unwanted users from replying to your message. To accomplish this follow these steps:

  1. Go to Mandrill.com and Login > Outbound > Rules sub-tab
  2. + Add Rule

Use the Following Settings:

if a message [is sent] and [any] of the following conditions are met:
[recipient's email] [matches] *@mywebsite.com
then do this:
[reject message]

Now, any emails that attempt to send to any email with the domain, @mywebsite.com, will be rejected by Mandrill. Once the emails are rejected by Mandrill Freedom then automatically puts the email address that was rejected into the Blacklist and Bounced > Invalidated tabs.
