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'

    HI EVERYONE,

    It seems that on Friday Yahoo moved to goalpost on what was required for sending them emails (again). My private exchange server customers don't have any issues once SPF is implemented, but M365 are going to need the whole kit and kaboodle.

    I'm working through my paid clients right now, and for each one, I have been able to follow a specific set of steps to create all the records in such a manner that I should be able to post the definitive list of what to do. It might not be until tonight that I post my solution, so if you want to work on it yourself, you need to setup all 3, SPF, DMARC, and DKIM.

    The default domain does NOT affect this. I found my GoDaddy M365 client it would not let me change the default domain, and I was still able to implement the fix.

    -Brad

    Yeah I see that. He seemed to have a workaround - but when I attempt it I end up at Godaddy and can't edit domains to make the primary domain the default in 365 to hopefully solve the problem. He got to the admin center but I get pushed back to Godaddy.

    "Yes, I just logged into my client with GoDaddy, after you get into the admin.exchange site, at the very bottom along the left is a link to Microsoft 365 admin center, clicking on that I was able to get to the root admin center for my client that has GoDaddy as a reseller."

    Read Brad's reply to me 2 posts above yours. Redirect to GoDaddy is normal. I'll leave this to Brad because I have never dealt with GoDaddy DNS management. Mine is a direct subscription from Microsoft and DNS management is at admin.microsoft.com

    Brad,

    When I attempt that by clicking on Microsoft 365 admin center link I simply get pushed back into the Godaddy "Email and Office" management screen that doesn't actually allow any real management.

    Perhaps if you gave a direct link it would work?

    I didn't know that. Thanks. I have subscription directly from Microsoft.
