Hello,

Can someone provide an example on how to actually use the LDAP feature of
Windows 2003 SMTP (No Excange). You can supposadly use this to expand
address lists. Can this be used with ADAM?

Another related question I have is: Can you reject messages at the Protocol
Level (Return a 550 error) based on information in either an LDAP or Active
Directory with Windows 2003 SMTP. Is there an add on that can do this? I
don't want to accept messages and the generate an NDR. I want to refuse them
during the SMTP conversation.

Thanks

Bill

You can use ORF EE, www.vamsoft.com, if you need a live LDAP directory
lookup for recipient validation. It does expect the Exchange schema
modifications to be made to AD or ADAM (giving you the proxyAddresses
attribute), but you can do this without installing Exchange.

Or, if you run that LDAP lookup separately (using LDIFDE and Task
Scheduler, for example) and export to a simple text file of e-mail
addresses to validate against, you can use our free 5XXSINK at:
