Adding Approved or Blocked Senders for Exchange 2013


You can block and approve Domain/IP's or Email Addresses for Hosted Exchange within the Control Panel.

As a rule, you should not whitelist your own domain or addresses as this will leave you open to spoofing attacks and receiving spam from impersonators.

  1. Log in to the Control Panel with your reseller account (https://controlpanel.hostedservices.com) and then log in as the relevant customer.
