Last Night i was adding a disclaimer for our company. I used imsext.dll with exchange 5.5. SP4 (following these intructions)
The first step was of course registering the .dll then Configuring exchange Internet Mail Service to:

Routing: Reroute incoming SMTP mail with send to: ourdomain.nl route to: <inbound> (this was already set of course)

Routing restrictions are set to: Host and client with these ip addresses (list is empty)

As shown on the website I added the path to the .dll
(instead of the table, use the custom routing program)
Path = C:\exchsrvr\CONNECT\MSEXCIMC\BIN\imsext.dll
(afterwards i unchecked it again)

I also added these keys:

A string value named NonRoutingExtensionDLL in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters

Its value:
C:\ExchSrvr\CONNECT\MSEXCIMC\BIN\IMSEXT.DLL

And a string value named OutBoundAppend in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters\Extension
The text for the disclaimer was added to the last string.

Retstarted the Internet Mail Service and sent a test mail to a external address. This worked no problem.

The problem:

I also sent an e-mail back and then i was confronted with this problem:

Does anyone know what went wrong? I know we are not blacklisted so this can't be a problem.
