Any ideas? > > Looks like you're trying to connect to a NAT'd public IP address from a private internal address. I would suggest one of the following options: 1. Set up an "internal" dns server, or configure your DNS server to support views so that all internal clients see the private rather than the public ip address of the mail server 2. Push out a static hosts file to each client machine with a host entry for store.knifecenter.com that points to the private address of your postfix box. That should be enough to get you started. You can learn more about views in BIND 9 here: http://sysadmin.oreilly.com/news/views_0501.html As far as pushing out the hosts file, you should be able to script that action.
