What software is this firewall running? At my previous job, we were running Sophos PureMessage, which had no native capability to validate recipients. However, the system was flexible enough that there were two rather simple methods of introducing recipient validation. Since the product used sendmail as its MTA, we set up a job to build a full list of recipients (users and aliases), and create a new virtusertable on the filtering host. Another option would have been to create a "list" of addresses in the products UI, and then create a rule that rejects recipients not in that list. Whatever you're using almost certainly will allow you to do one of those two. I never saw a product that wouldn't, when I was evaluating different solutions. _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
