but it now doesn't runs anymore with Outlook 2003 due to a Microsoft bug . This bug is reported in the article 872896.

SYMPTOMS
When you send an e-mail message in Microsoft Office Outlook 2003, the From field in the e-mail message that is in your Sent Items folder may not contain any e-mail addresses. Also, you may receive a non-delivery report (NDR) message in your Inbox folder that is similar to the following:
Your message did not reach some or all of the intended recipients.
Subject: test
Sent: 6/30/2004 1:48 PM
The following recipient(s) could not be reached:
'User@Domain.com' on 6/30/2004 1:48 PM
None of your e-mail accounts could send to this recipient.
CAUSE
This issue occurs if all the following are true:• You are using Microsoft Office Outlook 2003 Service Pack 1 (SP1).
• You are using either a Post Office Protocol version 3 (POP3) account or an Internet Message Access Protocol (IMAP) account.
• The e-mail message was sent to one or more people who are not in your domain.
• Outlook 2003 is configured to receive an NDR message for all recipients.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Currently, there is no resolution for this issue. Because the e-mail message was not delivered to any recipients, the fact that you have an empty From field in an-email message that is in your Sent Items folder would be known only by you.
