Thanx for the info.

 

SMTP only part of IIS on ISA.  Did you mean to say install GFI
MailEssentials on the ISA server and not IIS?

Get IIS off of ISA.

 

Put the GFI software on the IIS server, allow ldap from it to a DC.

Is it possible to have the above search the AD for a recipient and drop
the incoming message if the search is null?  We use GFI MailEssentials
and it performs this task very well using LDAP.  However, I want to drop
these messages on the edge - before they hit the internal GFI apps.  If
not IIS SMTP VS, would you know of any other product that sits on the
edge weeding out directory harvesting attempts?
