I've got a bit of problem with my postfix server. I had it working once and now it's throwing NOQUEUE: reject: RCPT errors int /var/log/maillog. Here's the output of postconf -n:
I've Googled the error and tried a couple of fixes to no avail. This is a CentOS 5.3 VM. I've got another postfix server on another VM on the same machine that works fine, however, and this is a weird thing, if I email the VM with the borked postfix server from the one with the working postfix server the borked one returns an error saying "mail for buttonhost.net loops back to myself" even though two different TLDs point to each VM (and each have completely independent public facing static IPs). I could just be missing something stupid and easy ...
What are the hostnames and domainnames for both servers, and what happens when you dig each hostname on each machine?
The one with the busted postfix is buttonhost.net the one with the working postfix is one-button.org. Here's the output from a dig on my local machine:

The canoical hostnames are webhost1 (for buttonhost) and demoman (for one-button) but these aren't actually used in from the outside world.
