Protocol Event Sink

| Junk Mail 2005-11-24, 5:54 pm |
| I am not a C++ programmer, but still I need to create a 'White List
function' on my SMTP Server at protocol level, because I need to terminate
the SMTP connection...
I tried to build the ShieldsUp Protocol Event Sink with ATL
http://msdn.microsoft.com/library/e...dc8d82c93d4.asp
I can compile but, I can't register the event
Can anyone help me?
I can't attatch the project, but if you can help me, I will send the Zip
file

| Now I got the sample to work... not easy for at none C++ guy :-)
I can now close the smtp connection with this code, but how do I get til
senders ip address?

I got this working as well. It uses Active Directory as a whitelist
container.
The difficulties exist at the documentation level. MS did not document this
too well, since it would be against there own Exchange product

You could read a property from IMailMsgProperties:
CHAR szBuf[100];
if (pMsg) // This interface pointer will only be initialized after "MAIL
FROM: <user@domain>"
{
hr = pMsg-> GetStringA(IMMPID_MP_CONNECTION_IP_ADDRE
SS, sizeof(szBuf),
szBuf);
......
}
where IMMPID_MP_CONNECTION_IP_ADDRESS is defined in mailmsgprops.h (Platform
SDK).
