    MX toolbox says the DNS serial numbers don't match, which looks like it's a dodgy dns setting.

    Hi Michael.

    When my server crashed 3 weeks ago, i had to perform a fresh install.
    I must have typo'd when i set the name servers up.
    At registrar level I had NS and NS1, but on the server i had NS and NS2.
    I altered the DNS at registrar level to reflect NS and NS2.

    MxToolbox is not currently showing any DNS errors, so it's something that I'll have to watch

    I am happy to see you were able to determine the mistake you made with your DNS configuration. Thank you for updating us with the outcome, and feel free to update us if you encounter this issue again after correcting the DNS problem.

    Thank you.
