When POSTing a contact form, the e-mail stays local to the virtualmin server. I have e-mail disabled for the domain in virtualmin. I also have the MX records for Google apps in the DNS zone file local on the server.
Even with this setup, I cannot get the server to look outside itself for this domain.
Great that was it! it was still in there, which I had commented out earlier I just didn’t run the postmap command. I thought by restarting the postfix service it would reload the config files.
