Adapt these ideas to your situation: http://www.unixwiz.net/techtips/postfix-exchange-users.html extract_e3k_recipients.tar.gz from http://www.postfix-book.com/downloads.html "A collection of scripts to extract valid recipients from a Microsoft Exchange servers Active Directory. It will also build a map for Postfix to be used in recipient validation."

Verifying addresses on Exchange/AD from an edge server
Hi, While I have a nice edge server now that handles inbound spam/av using OpenSMTPd, Spam Assassin and ClamAV, I want the OpenSMTPd server to validate legitimate email addresses on initial connection before accepting, processing, and relaying them onto the primary Microsoft Exchange Servers. Now I have seen some examples (over on undeadly) of LDAP to an openldap instance but don't think that will work in this case? AD does present and permit LDAP lookups and provides 'proxyaddresses' of smtp addresses associated to the users accounts but I don't think there is any facility (that I could find) to perform this for each connection (similar to table myaddresses ldap://activedirectory). Has anyone solved this or know how to achieve this? Maybe even a script that I can run say every 3 hours, a bit of hackery, uniq and a makemap would get me by as well. Thanks, Jason.
