OK, I do have a problem after all. The editing I did to httpd.conf to fix the problem originally, apparently wasn't the only thing wrong. I deleted one domain, and recreated it, then made the changes to the DSN Zone that I had to do before(Virtmin still puts that @ symbol in there, and that just won't wotk). But then checked httpd.conf, and this time the IP address WAS the same as the existing two that DO work.
I had just ONE thought as to why it isn't working: When you delete a Comain, then recreate it immediately, will it still have a propagation delay of x hours, perhaps due to the new serial number of the virtual server? If so, perhaps this will start working tomorrow?
www.intodns.com says all the settings are correct.
I am SO confused at this point, lol.....
