If you're incoming mail server is sending hard bounce replies back to Luminate, it could mean that your email server is expecting the sender to be from within your organization domain, but instead it is being sent from an unknown server (Blackbaud). Whoever manages your incoming email settings will need to authorize our servers to serve your domain.

Please contact the appropriate software vendor or IT professional for assistance with this process or issue, which is beyond Blackbaud's scope of support.
