      Just installed the latest PFS with postfix to run as a replacement mail relay for our aging ClearOS install.

      But I can't get it to work in it's simplest form!

      I have added my domains and the host to which they should be routed

      I have added my networks ( my server/24 network and even my own desktop for testing )

      Whatever I try I get

      "Sender address rejected: Domain not found"

        OK..

        removed our local DNS server entry, keeping just google servers and it works now.
