Data Protection Manager 2007 and Data Protection Manager 2010 notification emails may not be delivered to the configured list of recipients although individual test mails are delivered successfully (Options -> SMTP Server -> Send test mail). When you try to send a test mail to a group in this scenario you get the following error:
The SMTP server reports that the From address is not valid. (ID: 527)
Check For appropriate permissions to send via SMTP to the specified server.
Regardless of the actual error message, it can be misleading. The first thing to do is check the way the group is typed. The recipient addresses should be separated by commas like this:
If any other separator is used in place of a comma (e.g. a semi-colon), then you will get the above error.
Use commas as the separator for e-mail addresses.
Subscribing to Alert Notifications clearly states that the separator should be a comma, however please note that e-mails of recipients for DPM reports need to be separated by semi-colons and not commas. This is used by SQL Server Reporting Services and does not go through DPM directly. For example:
