INTRODUCTION
This article describes how to configure Sybari Antigen 8.0 for Microsoft Exchange to filter e-mail messages that contain only a space character in the Subject field or in the Sender field.



MORE INFORMATION
You may experience behavior in which Antigen does not filter certain messages that appear to have a blank Sender field or a blank Subject field. You experience this behavior after you configure Antigen to filter these kinds of messages. This behavior occurs if the Sender field or the Subject field in the e-mail message contains only a space character. In this situation, the field appears to be blank. However, the field actually contains a character. To configure Antigen to filter these kinds of messages, follow these steps:
 * 1) Start the Sybari Client program, and then connect to the server that is running Antigen.
 * 2) In Shuttle Navigator, click FILTERING, and then click Content.
 * 3) In the Content Fields work panel, click Sender-Domain.
 * 4) Click Add, type Unknown in the Content Filters work panel, and then press ENTER.
 * 5) If you want Antigen to remove e-mail messages that contain only a space character in the Sender field, click Purge: eliminate message in the Action list.
 * 6) Click Save.
 * 7) In the Content Fields work panel, click Subject Line.
 * 8) Click Add, type Unknown in the Content Filters work panel, and then press ENTER.
 * 9) If you want Antigen to remove e-mail messages that contain only a space character in the Subject field, click Purge: eliminate message in the Action list.
 * 10) Click Save.
