  1. Yes, as of yesterday afternoon, it looks like Videotron started accepting our mail again. Good deal.

     

    akgh519, we haven't had any issues delivering mail for @gci.net users. Their servers have accepted everything we've sent and once a message is received, we don't have any visibility into where it goes. So, that means it's likely either in your SPAM folder or they are quietly filtering it. I'd recommend contacting your email administrator to see if they can find out where they're going.

     

    Vesuviano,

    It looks like your address is an @ericsson.com address. Much like @gci.net, messages we send to that domain are being accepted by your mail server. If they aren't showing up in your Inbox, they'll likely be in your SPAM folder or they've been filtered. I'd also recommend talking to your email administrator if you can't find them.

  2. OK, here's an update:

     

    KPN users: The fix has been applied and I'm currently sending through all held mail. In the next couple hours I'll be re-enabling accounts that were previously invalidated.

     

    @videotron.ca and videotron.qc.ca users: Videotron has not responded to our email and continues to defer messages. While I'll continue to try to contact them from my end, we might have success if you contact them as well and request that they stop deferring email from our domains.

     

    Vesuviano, what is your email domain?

  3. PnavE_81,

    Yes, the two problems are definitely related. I'll likely be administratively validating the accounts once the issue with KPN is corrected.

    And on that topic, we've made some progress with KPN. They've submitted some changes to their receiving systems that should solve the problem. They say it could take several hours to go into effect, but I think we might have a resolution later today.

    Are these issues still being caused by sending too many emails with invalid addresses, and GS's server having reputation issues because the receiving servers are suspecting a directory harvest attack? And are GS's logs of errors from these servers still not being automatically parsed nightly for potential blacklist and throttling issues that arise as a result? Please say no.

     

    No, that's not the case. Our transactional servers have excellent sending reputation and we have measures in place to avoid sending to invalid addresses. Sending email is still an inexact science because of the massive variation in how each ISP and domain configures their servers, particularly smaller providers.

     

    For the KPN users, I've been in contact with their email team and we're working on the problem. Hopefully we'll have a resolution soon!

    Videotron.ca users, I'll send an update when I have one. Finally, akgh519, I'm not seeing any issues sending to @gci.net right now. When I have time later today I'll send you a PM and get more details to see if I can identify if there's an issue.
