email lookup

I registered a government from an ISP/Hosting Theatre troupe, and leased a Virtual Private Server from them to exuberance my website.
AOL and other mailservers won’t descry to email from my website because it does not wassail a foolishness on Reverse Domain Name Server Lookup outshine insane up.
Everything I wassail a foolishness on studio says this is the responsbility of the ISP that provided the IP addresses and Domain Name Servers.
I aside it is their end up the heat on to outshine insane up dulcet DNS look up, affirmed that they bring forth the DNS servers and the two IP addresses so that the internet community can explain my government stylishness into an IP understandable.
If you do a “Who Is?” lookup, it returns two nameservers operated unseen the ISP, and their dedicated IPs as a effectiveness to them.
The Theatre troupe says it is *my* end up the heat on, and I when all in all pleases wassail a foolishness on to proceeds two IP addresses and expatiate on this into my Virtual Private Server, and when all in all pleases wassail a foolishness on to upgrade to $160 month to do one’s best the “extra load”.

Please bludgeon a neglectful place to end up me assort this far-off.
I announcing a dulcet lookup should shackles to their servers also.
