I have ZCS 8.0.6 installed and running fine. I'm using a web server that has a form system to create web-based forms that will send an email to a recipient upon submission. If I specify my gmail account in the form as the delivery address it comes through no problem. However if I specify email@example.com (where domain is is my fqdn.com) address I receive the below error in Postfix on the web server that is submitting the form:
I assume this is some check in the MTA in ZCS causing it to bounce. I've set a FQDN address in my reply-to in the form itself and it still has the same problem.

I also disabled reject_non_fqdn_sender via Global Settings -> MTA and it still had no effect. I'm still bouncing.
Is this something I should address with Postfix on the webserver (setting the fqdn or looking into the hosts/hostname)? Or is there something in ZCS that I can uncheck to allow this message through?
