Starting this week, our emails to yahoo and aol accounts are not being delivered, but emails to other email accounts are working. Here is one of the yahoo error message: 1/12/2024 9:27:16 PM - Server at SJ2PR02MB10076.namprd02.prod.outlook.com returned '550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError' 1/12/2024 9:26:15 PM - Server at mta5.am0.yahoodns.net (67.195.204.73) returned '421 4.4.2 Connection dropped due to SocketError'

And here is the aol error message: 1/12/2024 9:27:38 PM - Server at PH0PR02MB7367.namprd02.prod.outlook.com returned '550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError'

    Does your issue have something to do with mailing list?

    Sorry if this is the wrong thread. The issue is that I cannot send emails to yahoo addresses so I thought this is the same issue.

    Serveur de génération : AM9P194MB1315.EURP194.PROD.OUTLOOK.COM
    Total retry attempts: 10

    Remote server returned '550 5.4.300 Message expired -> 451 This mail has been deferred because the sender is sending too much mail for its authentication status. Please set up DKIM aligned to the From: domain. See https://senders.yahooinc.com/smtp-error-codes#authentication-failures for more information.'

    I checked the Yahoo link, but I don't really know what DKIM is, and I'm not sure I have access to it under just hotmail.

    >> I have this issue but with a hotmail address.

    >> And the issue is still here today.

    Your problem isn't DNS related. What is the issue?

    I've read this thread and all the replies seem to be about custom domains. I have this issue but with a hotmail address. Am I out of luck? I've found another thread where the issue was seemingly relayed to Microsoft but that was in November last year. And the issue is still here today.

    Ok, I'm still a little confused (I'm blonde) about how your domain email is tied to your Hotmail account. If you send an email from hotmail, does it look like it is coming from your hotmail account, or does it look like it is coming from your soulsoundyoga.be email address?

    (you can send me an email - brad _AT_ grorud _DOT_ org and I can see for myself)

    Have you tried logging into your soulsoundyoga.be directly and seeing if you are able to email yahoo or aol accounts from there?

    If you send me a test email, also send me as a separate message a forward or screenshot of the bounce-back message.

    -Brad
