Scenario 2: Unrecognized Sender

Here, a Webmail is sent from an unrecognized address (such as mysteryman@hotmail.com). The NBA detects the Webmail and passes it to a policy engine, which applies the External Sender’s policy. When the Webmail is blocked, a notification email is sent externally, through the NBA, to the sender’s Webmail address. The NBA detects that the notification email was generated by CA DataMinder and exempts it from policy processing.

Example NBA notification email: Unrecognized sender

Using Internet Explorer, a user sends a Webmail (1) to another Hotmail recipient. The NBA (2) detects the Webmail and passes it via the Socket API (3) to a policy engine for processing (4).

Because the sender cannot be mapped to a CA DataMinder user account, the policy engine applies the External Sender’s policy to the Webmail. After applying email triggers, the policy engine calls back to the NBA to block the Webmail (5); the Webmail is duly blocked (6).

The policy control action is set to ‘Block with Notification’, so the Socket API (3) generates a notification email (7). The From: field is set to Compliance@Unipraxis.com. The corporate Exchange server (8) then forwards the notification email to the original sender’s Hotmail address.

The notification email passes through the NBA (9) on its way to the Hotmail server (10). The NBA automatically exempts the notification email from policy processing.

The original sender (1) sees the notification email when they next view their Hotmail inbox.
