5.7.1 Unable to Relay
Posted by Carlos Rios on 15 November 2017 02:09 PM

This is not an error generated by the Reflexion.

This indicates that the receiving server is misconfigured to believe that email is trying to be sent through it instead of received by that server.   

To resolve this issue, please make sure that the primary domain in Reflexion is listed under the Accepted Domains tab by going to: 

Org Config > Hub Transport > Accepted domains

ERROR: This domain name does not match domain registered in the license key file (, allowed domains:,localhost, please change the product path to match the domain under Admin CP > Settings > General Settings
This product will not work properly unless untill that value is changed.
