The administrator can encourage users to send secure emails or regular, not secured, emails. They can exempt messages between certain domains from Zivver encryption and authentication. For addresses in such domains, Zivver shows the suggestion that it is not necessary to enable Zivver for this message. But the sender can still enable Zivver for that message.

For example, the mail system can deliver messages to certain domains through an internal relay.

1. Open Business Rules in the The Zivver WebApp.

2. Scroll down to Trusted and Untrusted domains.

   Don’t you see the “Trusted and Untrusted domains” block?
   Please contact your Customer Sucess Manager or support@zivver.com and request the usage of (un)trusted domains.

3. Make the changes:

   • Add trusted domains under the Trusted domains block.
     e.g. zivver.com
   • Add untrusted domains under the Untrused domains block.
     e.g. untrusted.org
