554 5.1.0 The Sender'™s Address Was Not Allowed

This is the response our platform returns if you are trying to send a message using a domain or address that is not present on a server's Deliver From Whitelist.

The Deliver From Whitelist is a security feature for SocketLabs On-Demand customers.  The Deliver From Whitelist allows for a server to be restricted to only accept messages for delivery that utilize specific addresses or domains in the From field.  Messages from addresses or domains that are not on your list will not be sent. This applies to automated messages as well.

Addresses and domains can be added or removed from the Deliver From Whitelist in the On-Demand Control Panel.  To edit the Deliver From Whitelist for your server follow these steps:

1) Log-in to your On-Demand account:  [ ]

2) Select the "View" button next to the server for which you'd like to update the Deliver From Whitelist

3) Using the top menu bar click on "Configuration"

4) Select "Configure Deliver From Whitelist" from the Configuration drop-down menu.  

Note: Domains are added by using the "" syntax.

*Addresses and domains may be added by a SocketLabs administrator and these cannot be removed. For more information on the Deliver From Whitelist please see our knowledgebase article [ ].
