SYMPTOMS
When an SMTP message that is routed through the Lotus Notes SMTP message transfer agent (SMTPMTA) to the Exchange Connector for Lotus Notes and then to Microsoft Exchange 2000 Server, "@NotesDomain" is appended to the sender's SMTP address. For example, if a sender's address is someone@example.com, the address will appear in an Exchange client as someone@example.com@NotesDomain. This behavior causes all replies to these messages to be sent back to the Exchange Connector for Lotus Notes instead of to an Exchange SMTP route.
CAUSE
This behavior was designed to enable replies to downstream Lotus Notes domains. There is no sender validation in the LSMEXIN process to distinguish between a downstream Notes domain and a message from the SMTPMTA.
RESOLUTION
To resolve this problem, follow these steps:
- Upgrade the Exchange server to Microsoft Exchange Server 2003.
- Install Microsoft Exchange Server 2003 Service Pack 2 (SP2).
- Upgrade the Exchange Connector for Lotus Notes to the latest Web Release.
To obtain the updated Exchange Connector for Lotus Notes, visit the following Microsoft Web site:
Note Make sure that the SMTP address of the Exchange user is synced to the Internet Address field of the person document that is created by the Dirsync process in Exchange Connector for Lotus Notes.
To do this, modify the following mapping tables:
Edit the following SMTP address in the Amap.tbl mapping tables. You can find these tables under the Exchsrvr\conndata\dxamex folder path:
InetAddr 128 proxyAddresses(SMTP:)
Edit the following SMTP address in the Amap.tbl mapping tables. You can find these tables under the Exchsrvr\conndata\dxanotes folder path:
InetAddr 128 InternetAddress
Notes- For the line in the Amap.tbl file of the Dxamex folder, if the word SMTP is uppercase, the primary bold SMTP address syncs from Exchange to Notes. If the word smtp is lowercase, one of the secondary smtp addresses will be synced. Both of these entries are required for the sync to work.
If you only want to sync in one direction, such as to sync an Exchange server to a Lotus Notes server when the Lotus Notes server is the SMTP gateway, you have to change the SMTP address in the Amap.tbl file of the Dxanotes folder to the following entry:
InetAddr 128 InternetAddress 1
The "1" at the end of the SMTP address sets the value to read-only. Therefore, the Dirsync process will not write the SMTP address of the Notes user to the contact in Active Directory.
- After you have made the changes, restart the Microsoft Exchange Connectivity Controller service and the Microsoft Exchange Connector for Lotus Notes service. Then force a full reload of the Dirsync process. You can force the reload in both of directions, or you can force the reload only from Exchange to Lotus Notes if you want to sync only one direction and Lotus Notes is the SMTP gateway to Exchange.
Note After you upgrade to the latest Exchange Server 2003 post-Service Pack 2 Web Release, "@NotesDomain" will still be appended to the sender's display name of incoming e-mail from external Internet domains. However, this behavior will no longer affect message flow.
STATUS
This problem occurs only if Lotus Notes is configured as the inbound SMTP mail gateway from the Internet. This is not a supported configuration of the Microsoft Exchange Connector for Lotus Notes before the Microsoft Exchange Server 2003 post-Service Pack 2 Web Release.
MORE INFORMATION
After you upgrade to the latest Exchange Server 2003 post-Service Pack 2 Web Release, the Exchange Connector for Lotus Notes now supports an IBM Notes Domino server as the inbound SMTP gateway during the migration process to Exchange Server. For a longer-term solution, we recommend that you point the inbound SMTP gateway to Exchange Server.
You have to sync SMTP addresses from Exchange to Notes to the Internet Address field of the Person document when Domino is the SMTP gateway. This is because the Domino SMTP MTA uses the Internet Address field to resolve the user’s SMTP address. If the Internet Address field is not populated, you see the address and display name change, and you experience the behavior that is mentioned in the "Symptoms" section.
