Thread: Email/PTR

  1. #1

    Email/PTR

    I have a Windoze box with three ip addresses and running Mailenable Professional as the mail server software. I do not run any DNS, rather I set up the domain to point to my server at the registrar. All of a sudden I'm getting returned mail, "This server requires PTR for unauthenticated connections". When I run the diagnostics on the mail server it says that none of my ip addresses have reverse dns....... I'm confused, what do I need to do at the registar and server level to feel joy again? Thanks in advance.
    PS-- I'm not on any blacklist and this is happening at more than one ISP.

    You need to contact your provider and ask them to set a PTR for your IPs.

    You need to set RDNS for the mail server IPs. Your host provider will be able to do this.

    Thanks for the response, this is a co-lo, I'm asking them to set it up for me? Thanks again!
