See http://mimedefang.org/kwiki/index.cgi?Exchange2Access for scripts that pull the entire user base from an Exchange server and format as a sendmail access.db. This allows you to set the default for your domain to 550 User Unknown, and explicity allow any valid e-mail addresses. If you have more than 1000 users on your system, you'll get errors - you can either modify your exchange server to allow more than 1000 records in a query response, or contact me off list for my cutomization to the script to use a paged ldap query.
