Another solution is to build a virtusertable db on your MX which contains a list of all your valid usernames and reject anyone that isn't in it with an unknown user error. This virtusertable can be updated periodically via a combination of cron, ssh, and scp. This is what I'm doing at the moment because at the time I implemented it it was the least drastic change to my existing setup... ___________________________________________ Michael Sims Project Analyst - Information Technology Crye-Leike Realtors Office: (901)758-5648 Pager: (901)769-3722 ___________________________________________ _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
