(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows Registry
When you try to use the Microsoft Exchange Server 2003 Always-up-to-date (AUTD) Notifications feature to help keep Microsoft Outlook Mobile Access mobile devices up to date, you are unsuccessful. Mobile devices do not receive the Simple Mail Transfer Protocol (SMTP) notification messages that are sent from your Exchange Server 2003 computer.
This problem occurs because Exchange Server 2003 sends notification messages that contain a blank From field to the mobile devices. Some wireless carriers block the specially-formatted SMTP messages because they contain a blank From field. Some carriers block all messages that have blank RFC-821 From fields because some unsolicited commercial e-mail (UCE) messages, also known as spam or junk e-mail, contain blank From fields.
To resolve this problem, modify the registry, and then apply this hotfix. After you apply this hotfix, you can create a static From SMTP address that Outlook Mobile Access (OMA) can specify in the X-Sender header while it composes the notification message body.
