    Is it possible to leave the actual message as well?

    That is your assertion, DC. Don't shift the burden of proof. It is entirely
    your responsibility to prove your statement.

    Maybe someday you will.

    If you took your time, you wouldn't make so many errors.

    That is quite weird.

    Fallacy of extended analogy. You cannot assume that two different situations
    in an argument about a general point constitutes a claim that those
    situations are analogous, DC.

    Scandalous dishonesty.

    Have a valid mx record? That's a joke right?

    *yawn* Who doesn't have a hunch there is probably some issue with dns or my
    primary mx.

    That's your problem.

    Have you ever known what else it can be, DC?

    Argumentum ad antiquitatem, DC. Nothing is 'good' or 'true' or 'correct'
    merely because "that's the way it's always been."

    > Will.


    Classic inconsistency.
