554 5.7.1: Relay Access Denied

Product: modusCloud


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


ModusCloud is a closed relay system. This means that all mail going through the 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 in modusCloud.

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 receives the relay access denied error messages is listed in this section of the platform.
  • If the account is a functional account, make sure the account is also listed under Functional Account tab.


          If you just added a new user in the last hour or enabled a relay on the Domains tab, your changes might have not taken effect. Give any enabled domain or added users 30 to 60 minutes to properly propagate on the platform. If you continue to receive this error message after trying these steps please contact Vircom support.
