I need someone to tell me how to create all my DNS entries so that I do
not get errors. I need forwards, mail, and reverse DNS entries.
OK FOR EXAMPLE IF MY:
Name servers are:
ns1.nbc.com 111.222.333.444
ns2.nbc.com 111.222.333.555
My domain is www.abc.com
IP is 111.222.333.444
net mask is 255.255.255.0
I also want my POP and SMTP to be "abc.com"
What would all the DNS lines look like for such a vertual site? server?
Currently, I have the following for "abc.com"
www.abc.com forward 111.222.333.444
abc.com forward 111.222.333.444
abc.com mail highest abc.com
111.222.333.444/255.255.255.0 Reverse abc.com
I have the above formats but I keep getting an error and slow e-mail
sending. The report from http://www.dnsreport.com shows:
" ERROR: One or more of your mail server(s) have no reverse DNS (PTR)
entries (if you see "Timeout" below, it may mean that your DNS servers
did not respond fast enough). RFC1912 2.1 says you should have a reverse
DNS for all your mail servers. It is strongly urged that you have them,
as many mailservers will not accept mail from mailservers with no
reverse DNS entry. The problem MX records are:
444.333.222.111.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount:
0)]"
PLEASE HELP!
I do not think it matters but I have a Raq550.
