554 5.7.1: Relay access denied
Posted by Carlos Rios on 20 November 2017 06:43 PM

Why do I keep getting a 554 5.7.1: Relay access denied?

Proofpoint Essentials is a closed relay system. This means that all mail going through the Essentials platform must have a user associated with the platform, whether that be End-User, alias, or Functional Account.

To resolve this issue you will want to check a few areas on the platform.

  1. Check to see if the Domain has relay access turned on.
    • Go to Company Settings -> Domains then make sure the switch is turned on to green.
  2. Check the Users and Groups
    • Make sure the user who is getting the relay access denied message is listed in this section.
    • If the account is a functional account, make sure the account is also listed under Functional Accounts tab.

Note* If you just added the user in the last hour or enabled relay on the domain, your changes might have not taken effect. Give any enabled domain or added user 30 to 60 minutes to properly propagate on the platform.

If you still keep getting this error message after trying these steps please contact support.


ERROR: This domain name does not match domain registered in the license key file (cms.orlinpilot.com), allowed domains: support.excelmicro.com,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.
