Geographical Restrictions in Mimecast


Geographical Restriction policies allow you to operate a country-based whitelist or blacklist to limit which countries your Mimecast account allows emails from. Emails outside of the allowed country list are rejected.

You can use these policies to automatically reject emails from high spam sending countries.

Definition

You will need to first configure a definition to determine which countries to use as a blacklist or whitelist.

  2. Select Administration Console


  1. Go to ‘Administration > Gateway > Policies’


  1. From the Definitions dropdown, select Geographical Restrictions


  1. Select New Geographical Restrictions
  2. Set the Name for the Definition
  3. Select to Block or Permit the country list
    1. Block: Operates a blacklist. Any country on this list will be rejected.
    2. Permit: Operates a whitelist. Any country not on this list will be rejected.
  4. Add countries to the Select Countries list by selecting them and using the Add & Remove buttons
  5. Press Save and Exit


Policy

Once a definition is created, a policy will determine when the restrictions apply.

  1. Log into your Mimecast Account at https://login.mimecast.com
  2. Select Administration Console


  1. Go to ‘Administration > Gateway > Policies’


  1. Select Geographical Restrictions from the policies list


  1. Select New Policy

  2. Press Save and Exit


Only one Geographical Restrictions Policy will apply to an email. If you need to ensure a policy is picked, you should enable the Policy Override option within the policy.
