error message "Your message wasn't delivered. Despite repeated attempts to deliver your message, a connection to the remote server was closed abruptly.

Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that your email system is unable to connecto their email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

For Email Admins
This often indicates the recipient's firewall SMTP fixup setting or other firewall settings are preventing the SMTP protocol negotiation from succeeding.

For Yahoo: returned '550 5.4.318 Message expired, connection reset (SuspiciousRemoteServerError)(450 4.4.318 Connection was closed abruptly (SuspiciousRemoteServerError))'
3/8/2024 8:44:42 PM - Server at mx-eu.mail.am0.yahoodns.net (188.125.72.73) returned '450 4.4.318 Connection was closed abruptly (SuspiciousRemoteServerError)'

For sky: returned '550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError'
3/8/2024 8:39:33 PM - Server at 188.125.72.73 (188.125.72.73) returned '421 4.4.2 Connection dropped due to SocketError'

I cannot ask all my contacts that have yahoo or sky accounts to change their firewall settings. There seems to be a problem with Microsoft!

    Thank you for providing the Microsoft guidance, but I don't think most personal and small business users of Microsoft would understand any of this. I was only able to get my email working to send to yahoo as I had additional guidance from GoDaddy. The SPF was already set up, I set up the DKIM and I could immediately send emails to yahoo. I then tried setting up the DMARC and this stopped my ability to send emails to yahoo, so I deleted it. Leaving it for the moment as it is working, but Microsoft and Yahoo etc need to take note that the changes they are introducing are excluding people from using emails and must be damaging many small businesses, charities etc.

    Eleni - I am using Microsoft Office 2019 and your links only appear to refer to Microsoft 365 users.

    Do you have any solutions for those of us who are not using Microsoft 365 AND are not IT professionals.

    Your help will be greatly appreciated by a lot of us.

    I agree this is ridiculous expecting people with no IT skills using personal Microsoft products to find their own solutions. We don't have the funds to employ an IT expert. I could follow the GoDaddy instructions as my email is through them, but the Microsoft instructions are impossible with no IT knowledge.
