Multiple Notifications in Response to a Single Email

When an email activates a control trigger, the sender of the email can sometimes receive multiple warning or notification messages. This happens when CA DataMinder applies policy to multiple copies of the original email.

This can occur if an email is sent, via an email server with no server agent installed. In this situation, the following scenarios can result in multiple notification messages being sent:

• The recipients’ mailboxes are hosted on multiple email servers. Each of these email servers has a server agent installed. Policy is applied to the email each time it reaches the server agent on one of these subsequent email servers. This example is shown below.
• Two or more recipients have mailboxes hosted on the same email server. The ‘sending’ email server sends copies of the email to each recipient’s mailbox. The server agent on the email server hosting these mailboxes applies policy to each recipient’s copy of the email.

The two scenarios above are the most likely cause of multiple notification messages. But other configurations can also cause multiple notifications. For example, multiple copies of the original email may simply be routed through an email server hosting the server agent. Likewise, a non-standard journaling setup may result in the server agent failing to recognize a journaled email and applying policy to that email.

To avoid any of the above scenarios, we recommend that you install server agents on all email servers in the CA DataMinder enterprise.

Multiple notification messages example

1 A user sends an email and it transits through the email server (1a), undetected. The recipients’ mailboxes (2b and 3b) are on two separate email servers (2a and 3a).

2 and 3 An instance of the email arrives at each email server. Each instance is detected by an email server agent (2c and 3c) and triggers a warning notification.

4 Each email server agent then sends a warning message to the sender.

5 The user receives multiple notification messages in response to a single email.
