I've an issue on ALL the new installations I've done of SQL Backup 5.
They ALL fail on sending mail on error/completion. All old installations that have been upgraded work fine, but none of the new installations.
The new installations are all sql server 2005.
On all of them Database mail has been setup and are working when tested.
SQL Backup 5s mailsetup has also been done and tested OK from the GUI.
But every single job I schedule that try to send mail on completion or on error fails with this in the log:
Warning 151: MAILTO error: Failed to send mail. (5.7.3 Authentication unsuccessful. )
