Hi, am running webserver and mail server on T1 line. just had a new T1 line installed last weekend and the transition went smoothly. I left everything the same on Register.com associated with my domain name except the IP address that the name was pointing to.
The hostname is with register.com and I have it pointing to my IP address for my web and mail server for our domain name. Also, have the MX records pointing to the domain name of myserver.com and www.myserver.com
However, we started to have problems with AOL and them rejecting our email because of an incorrect Reverse DNS Lookup, or so the emails said. ALso a few other companies were rejecting our mail because of the same problem. THIS STARTED ONLY AFTER WE WERE ON OUR NEW T1, not the OLD ONE. I called my ISP and they said that I needed to go the register.com and instead of having Register.com's DNS servers (dns41.register.com and (dns42.register.com) be authoritative for my domain name, I needed to change them to my ISP's DNS servers ( ns1.deltacom.net, and ns2.deltacom.net and ns6.deltacom.net).
So I did this and within 24 hours, anything associated with my domain name has quit working. So as soon as I found this out, yesterday afternoon I changed my current DNS servers back to the ones from REGISTER.com. It hasn't been 24 hours but it has been 15 hours and they still haven't reset, I guess that will take a little longer.
1)Does anyone know what the problem could be here? Hopefully, this will resolve itself when the DNS servers across the net update and get the old DNS info back.
2) Also, what is the REfresh time under SOA? I changed this from 10800 seconds to 1000 seconds (the shortest that it would let me) to see if this would speed up the refresh time) (it didn't).
3) Does it always take 24 hours or longer for the DNS servers across the NET to update? as I can't tell if my reset is working until they do.
4) When I do a DNSstuff.com DNS lookup, I get
Searching for A record for designmca.com at g.root-servers.net: Got referral to J.GTLD-SERVERS.NET. [took 198 ms]
Searching for A record for designmca.com at J.GTLD-SERVERS.NET.: Got referral to ns1.deltacom.net. [took 200 ms]
Searching for A record for designmca.com at ns1.deltacom.net.: Server failure! [took 300 ms].
Does this mean that the 3rd entry ns1.deltacom.net is down? Could this also be related to my problem? This is my ISP and they have been having trouble the last few days. Or does this mean something else?
Thanks very much.
