[Google Admin Console] Spam setting: Add approved senders to bypass the spam folder Incoming email messages are subjected to Google's spam filters, so messages detected as spam are automatically placed in a user's Gmail spam folder. However, the Spam setting enables you to create an approved sender list to bypass the spam folder. You can approve specific senders based on the email address or domain. For instructions, see Spam setting: Add approved senders to bypass the spam folder. Approved sender lists can also be reused across different settings. For example, you can specify the same approved sender list in both the Spam setting and the Secure Transport (TLS) compliance setting, and it would modify the behavior of both settings. Note: If a message from an approved sender contains a virus or is part of an email attack, Google's virus filters will still prevent it from reaching your users. [Postini Admin Console]
