You need to chose a policy first. You may either deny or
allow hosts known to be within certain geographic locations.
It may be wise to pick a permissive approach by denying only a few countries
rather than the opposite. Note that you can totally deny-none
or allow-all and use this service just for monitoring purposes
The system can track and privately report you the geographic statistics
of your SMTP traffic. You need to declare the IP address
of yourSMTP server and verify your email address prior to getting your
account activated. May you wish to unsubscribe at any time, all data related to your
account will be deleted.
