Hello,

   When you say "authenticate " do you mean check to make sure the
recipient is a valid user or that you are doing actual username and
password to verify clients before mail from them is accepted ?

   If you want to simple valid a recipient you may want to rethink this
idea. During a dictionary attack your Active Directory server could
become unavailable do to the massive request for authentication from the
SMTP server.

Ideally you could install OpenLDAP on the mail server and twice a day
have a script pull down a list of users and create a address book that
your SMTP server can read.

Use OpenLDAP to query the AD server and bring down the e-mail addresses.

Michael.
