Beta Information and overview


The Geographical restrictions policy helps customers to prevent receiving messages from specific countries and regions.  Some industries may have either regulatory requirements or security concerns which require their mail gateway to implement.  The Geo policy will allow customers a simple way to reject or permit mail from IP addresses listed in our country specific IP database.


Mimecast will evaluate and apply all policies that are applicable.  'Allow' definitions will override 'block' in the case of overlap and can be used to make exceptions.


CAUTION: Applying the 'block' policy will reject messages in protocol and will be recorded under the Administration > Monitoring > Rejected queue.


Timeline and feedback

We are focused on providing an exceptional experience for our customers, so are look for candidates willing to participate in this beta, due to start from March 18th, 2019.  Interested candidates are required to email to register interest.
