Start / debug SMTP events in Windows 2008

Question

I have an SMTP Event Sink to handle incoming SMTP messages to perform special processing. In IIS 6 / SMTP, this receiver works as expected. In IIS 7 / SMTP, it does not work, although it seems to be successfully registered, as shown below:

c:\Program Files\Kryptiq Corporation\GW\Bin>regsvr32 SpoolFilter.dll c:\Program Files\Kryptiq Corporation\GW\Bin>smtp_sink_register.bat c:\Program Files\Kryptiq Corporation\GW\Bin>cscript smtpreg.vbs /add 1 OnArrival KryptiqSpoolFilter SpoolFilter.FilterObject "mail from=*" Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation. All rights reserved. Binding Display Name Specified: KryptiqSpoolFilter Assigning priority (24575 in 32767) ** SUCCESS ** Registered Binding: Event Name :SMTP Transport OnSubmission Display Name:KryptiqSpoolFilter Binding GUID:{C12ECB83-BF0A-46B4-823D-8C4D212F5238} ProgID :SpoolFilter.FilterObject Rule :mail from=* Priority :24575 (0 - 32767, default: 24575) ComCatID :{FF3CAA23-00B9-11d2-9DFB-00C04FA322BA} 

How can I debug this receiver and find out why it doesn’t process the email that goes into the SMTP pickup directory, but instead the email goes through intact? Are there IIS 7 requirements for SFC Event Sinks other than IIS 6, such as new permissions?

According to the URL http://social.technet.microsoft.com/Forums/en-US/exchangesvrtransport/thread/73fd85d0-66c4-4ffa-904f-0b0bcb521a31

IIS7 no longer uses the IIS SMTP event architecture, and instead you need to create an SMTP Receive Agent. (more information at http://msdn2.microsoft.com/en-us/library/aa563087.aspx )
