MDaemon 11 now requires SecurityPlus' Urgent Updates feature to verify the DKIM signature of the incoming message from us at Alt-N in order to be processed, for security purposes. This means you need to make sure DKIM verification is enabled if you wish to continue using this feature.
To enable DKIM verification:
- Click the Security menu
- Click Security Settings...
- Select DKIM Verification on the left pane
- Enable Verify Domain Keys Identified Mail (DKIM) signatures
- Click OK
Note that you can change the other options if you wish, but is not required to receive new Urgent Update emails.
Note that DKIM verification requires MDaemon Pro.
