Re: Blacklisting

I am running my small businesses on my own linux server in my basement, on a Rogers fibre business account and have seen no issues.

Back then, we had a hard time proving that our server was not a spammer. We had issues with outlook.com <http://outlook.com> (and other Micro$oft domains) as well as gmail.com <http://gmail.com> and yahoo.com <http://yahoo.com>. And Videotron still refuses to whitelist our IP address. They claim it is our message format which is not "compliant".

OK, back to the beach and the pool now...................................⛱️⛱️⛱️

    Hi Jean-Francois,

    I completely agree. One of my concerns is how this affects
    businesses,
    such as Canadian web hosting companies. I feel it would be easy to
    think
    "there's a problem with that company" when the 'problem' is not
    with the
    specific company at all.
