Approved senders addresses for Google notifications:
WARNING: We strongly recommend that you do not add your own domain/addresses or
popular domains to the Approved Senders list. Spammers routinely spoof these domains to
bypass the message security service filtering. Also, the service's anti-spam heuristics can
recognize legitimate messages from popular domains and minimize any false positives.
For more information on Senders lists, see the Approved and Blocked Senders chapter in the
Administration Guide .
