Frequently Asked Questions

Can I configure Domain Rewrite between multiple source tenants and a single target tenant?

Yes, Domain Rewrite supports a many-to-one rewrite scenario when all tenants are added to a single Domain Rewrite project. The best practice is to complete DNS and certificate requirements for all in-scope tenants during the initial project setup. If another source tenant is added to the project after the initial setup, you will need to fully disable rewrite in the project before re-enabling it. This is required so the transport rules can be recreated with the updated multitenant configuration.

important: Ensure that each tenant is only added to a single Domain Rewrite project. Enabling Domain Rewrite for a tenant in more than one project will result in mail flow issues.

Can I use a wild card certificate for Domain Rewrite Service?

Advanced Email Relay Service requires a single subject SSL certificate with both private and public keys attached. Wild Card certificates are not supported.
