    Anyone have an issue setting up the reverse dns on OVH when using cloudflare?

    I can't setup the reverse w/ cloudflare on because OVH sees CF IP and not the servers.

    I can bypass CF and hopefully get it set in OVH control panel, but when I turn CF back on it will reject the name and return the name on the server back to the default.*

    *Just realized why my 3 very small vps on OVH all lost the name I set. I just assumed that they moved my vps or something. I guess it was because those 3 vps go through CF.

    Is there a solution for this besides turning off CF for the server hostname which is a subdomain in my case.

    Yea, I read that. Doesn't having it not go through CF result in exposure of the IP address? I told them at SSDNODES to set the server name for me, it runs through CF and everything words great. Too bad that wasn't the same for OVH. Though, I do understand why it isn't working technically - it's pointing to a CF IP.

    What is the best solution, just using the generic OVH name or just having the subdomain not go through CF.

    Looks like playing around with it enough got the OVH generic name removed and it said "not configured" as the name. Then I entered my name and it took it. We'll see how this works out when I turn CF back on for funzies.

    Proper way is to have mail server not using same server as server origin i.e. outbound email of server sent from Amazon SES which is one of only 2 smtp 3rd parties which do not pass on original IP address in outbound emails. Other smtp providers pass the origin IP address in their mail headers.

    Other folks like to use mailinbox or mailcow on separate servers for the mail server. The same goal = not exposing the web server origin IP address which is protected by Cloudflare
