I think I'm having a basic problem, but I don't get to fix it...
I have domain.com and 1 server with IPs 220.127.116.11-4 and other with IP 18.104.22.168-4, ok?
then I have ns1.domain.com related to 22.214.171.124 and ns2.domain.com related to 126.96.36.199 (DNS and RDNS)
I also have domain.com and server1.domain.com related to 188.8.131.52 (domain.com DNS are configured as ns1.domain.com and ns2.domain.com)
now I want to have server2.domain.com related to 184.108.40.206... but I'm not getting to
I configured the second server hostname as "server2.domain.com" and configured (on server1 DNS), server2.domain.com to point to 220.127.116.11...
it works, but I don't get to send E-Mails from server2... I get messages like "Sender address rejected: Domain not found", "450 Client host rejected: cannot find your hostname, [18.104.22.168]"... but sometimes it works!
So I don't know what to do...
also, is there a way to make server2.domain.com points to 22.214.171.124 even is server1 is down (maybe setting a domain host on the domain?)?
they did 2-3 hours ago... is it needed to wait like more than that for propagation?
I have seen it take up to 12 hours.
