the DNS for domain name arcjc.org is hosted at ns1.digitalims.net and ns2.digitalims.net. Unless you have access to a DNS manager on their website, you will have to wait until Monday to contact them to change the record. Yes, RWW is hosted on your server. DNS at DigitalIMS points the hostname mailserver.arcjc.org to your server. It is just pointing to the wron IP right now. I see you are using MXlogix for mail filtering, so they are redirecting mail to your IP which I assume you updated at MXlogix after the T1 was swapped. If this is the case, it explains while mail works, but RWW doesn't.
