SYMPTOMS
Consider the following scenario:
 * You configure the Microsoft Exchange Server 2003 Connector for Lotus Notes to connect to a Lotus Domino messaging system.
 * The Domino messaging system receives an e-mail message from the Internet. Additionally, the Domino messaging system serves as the primary incoming SMTP gateway.
 * The message is delivered to a Microsoft Exchange Server 2003 user by using the Microsoft Exchange Server 2003 Connector for Lotus Notes.
 * The Exchange Server user replies to all recipients of the message. Additionally, the Exchange Server user adds a second external user to the message.

In this scenario, the return address of the message for the first external user is encapsulated as a Notes address that resembles the following address:

user1@internet.com@notesdomain

Therefore, the second external user cannot reply to the first external user.



RESOLUTION
To resolve this problem, install version 06.05.7917 of the Microsoft Exchange Server 2003 Connector for Lotus Notes or a later version of the Microsoft Exchange Server 2003 Connector for Lotus Notes. To obtain version 06.05.7917 of the Microsoft Exchange Server 2003 Connector for Lotus Notes or a later version of the Microsoft Exchange Server 2003 Connector for Lotus Notes, visit the following Microsoft Web site:

Hotfix information
After you apply the hotfix, you must enable the hotfix. To do this, you must edit the LME-NOTES section of the Exchconn.ini file to add a new HandleSMTPSender field. If the HandleSMTPSender field is not present, or if the value is set to 0, the default product behavior is observed. You must change the value of the HandleSMTPSender field to 1 to enable the hotfix.

After you enable the hotfix, the return address of the message is converted to SMTP format. In other words, as soon as a message arrives on an Exchange server through the Microsoft Exchange Server 2003 Connector for Lotus Notes, the Exchange server handles all additional routing of the message instead of sending the message back through the connector to be routed by the Domino messaging system.

A supported hotfix is now available from Microsoft. However, it is intended to correct only the problem that is described in this article.
