    Default RDNS problem

    Hello everyone,

    I host multiple domains on one server. And on one of the domains i host a client of mine is having his email rejected by another email server. I emailed the administrator of that server with the error message,

    Reporting-MTA: dns; mail.rndcomputing.com
    X-Postfix-Queue-ID: 4AFFE130C4BD
    X-Postfix-Sender: rfc822; efagan@efaganlaw.com

    Final-Recipient: rfc822; jtopor@wsnlaw.com
    Action: failed
    Status: 5.0.0

    command)

    You need to setup a RDNS record for efaganlaw.com. Currently it comes back as rndcomputing.com so it appears that you are spoofing efaganlaw.com which will cause problems for mail users of efaganlaw.com.

    Now currently the DNS for efaganlaw.com points to my web server (which also hosts multipple domains) , and the RDNS for my webserver points to my domain, rndcomputing.com (66.11.117.179)

    The MX record for efaganlaw.com points to mail.rndcomputing.com who's RDNS is 66.11.117.178.

    Now my question is, how can I have efaganlaw.com's RDNS point to efaganlaw.com when the IP for efaganlaw's RDNS is set to my domain, rndcomputing.com ?

    Do you host your own DNS? I'm guessing not, if you have an incorrect reverse lookup record.

    Contact them, they can fix that for you.
