550 Relaying is prohibited?? 1

[ProliantFan]

Last Night i was adding a disclaimer for our company. I used imsext.dll with exchange 5.5. SP4 (following these intructions)

http://www.msexchange.org/tutorials...With_The_IMS_Extension_In_MS_Exchange_55.html

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:

from isp e-mail server

----- The following addresses had permanent fatal errors -----
<me@domain.nl>
(reason: 550 Relaying is prohibited)

----- Transcript of session follows -----
... while talking to mail.domain.nl.:
>>> RCPT To:<me@domain.nl>
<<< 550 Relaying is prohibited
550 5.1.1 <me@domain.nl>... User unknown

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

Thnx
