how to configure an Exchange 2007 Edge transport to send email to exchange 2003 and set the SCL


If you just configure an EDGE server as a SMTP gateway device without a E2k7 HUB

server & relay mail to & from Ti servers anonymously with default config , the SCL

of the message determined & other relevant infor would not reach the Ti servers & hence lost:

Method 1 :  Using an account for Auth & Passing Exch50 information

=============================================================

 

 

—  Create a Domain account for Edge ( required for Authentication ) on the

Exchange 2003 side & add it to "Exchange Domain servers"  Group .

 

—  Configure a Send connector on Edge  to the  respective E2k3 Server  with

SmartHostMechanism = Basic Authentication  & used the domain account created in

Step 1  for the Credentials

 

—  Add the permission { ms-Exch-SMTP-Send-Exch50 ) on the NT AUTHORITY \ ANONYMOUS

LOGON on the respective send connector.

 

     for e.g. . if the Send connector is named as " To E2k3 " , the command to add

the permission would be

 

—  Add-adpermission "To E2k3" -user:"NT AUTHORITY \ ANONYMOUS LOGON"

-AccessRights:extendedright -Extendedright:ms-Exch-SMTP-Send-Exch50

 

— Now SCL would be sent to E2k3 box using the X-EXCH50 verb , after successful

authentication occurs , this can be verified by Protocol logs , Netmon etc  & also

Exposing the SCL values in MS  

    Outlook at the recepient end.

 

 

Method 2: Turn off Requireauth for XEXCH50 on Exchange 2003

============================================================

 

— Configure a Send connector on Edge  to the  respective E2k3 Server  with

SmartHostMechanism = ExternalAuthoritative .

 

— On the Exchange 2003 server , we need to disable the authentication requirement

to Propogate XEXCH50 . so set

 

HKLM\SYSTEM\CurrentControlSet\Services\SMTPSVC\XEXCH50\ Exch50AuthCheckEnabled = 0
