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'

    This is correct, it's a DNS setup issue. SPF / DKIM / DMARC are moving to being REQUIRED now.

    Everyone needs to get comfortable with these adjustments on their DNS provider. EX711592 calls this out directly.

    "If your admins have already confirmed that your organization's DKIM, SPF, and DMARC records have been established already, and your users haven't received the error code mentioned below in NDRs, then you can safely ignore this message. "

    There are things behind the scenes being implemented by Google, AOL, Yahoo - and they are a hard requirement now.

    Now then, those 3 things can each be done properly or improperly, which is another troubleshooting issue entirely.

    Hello Peeps,

    I had this problem and got help solving. Create a DNS TXT record: v=spf1 include:spf.protection.outlook.com -all

    Instant Gratification.

    Good Luck

    Brad, thank you for your reply. I do, usually, have access to my DNS settings, but there was a hiccup, maybe, whereby I was unable to edit for a a period of time. I seem to be able to do the edits again, now. I do have a convoluted email control situation, though. GoDaddy now has my domain, but my DNS settings are controlled by iPage who provides my web site (they are the ones who do not seem to know what to do with my DNS settings.) It's been a long story, but I'll be trying to fix the DMARC a bit later today, when things settle down with clients.

    Laura

    Yes, I was "off" on my comment; so sorry for the confusion! I was having problems with outgoing emails being delivered; my incoming emails are fine.
