Strengthening Email Ecosystem: Outlook’s New Requirements for High‐Volume Senders
I have a work email name @domainxxx.com it is a Google Workspace email address. I receive emails to this inbox also using support@ domainxxx.com from customers as well as email sent to myname@ domainxxx.com as the personal assistant to all the private clients. We have SPF, DKIM, and DMARC for name@ domainxxx.com our autoresponder emails send without issue. However, all 3 of the domain.com email addresses I use get blocked - this is awful, especially when I am REPLYING to someone who needs help accessing the courses they purchased and thet emailed me at support @domainxxx.com - even when I reply using the email address that has all the correct SPF, DKIM, and DMARC records we use without issue with our autoresponder - name@ domainxxx.com - It is bounced back. I cannot email our private clients who have paid $$$$$$$$s for private support from me using myname@ domainxxx.com - our tech department are at a loss as all the domain records are correct..... I get this error message:
The response from the remote server was:
550 5.7.515 Access denied, sending domain DOMAIN.COM doesn't meet the required authentication level. The sender's domain in the 5322.From address doesn't meet the authentication requirements defined for the sender. To learn how to fix this see:[ link ] Spf= Pass , Dkim= Fail , DMARC= Pass [link] [

Thanks, I will pass this to the tech team, but I am not using any templates, I am writing and sending emails from my google workspace email (gmail). In a normal compose screen how do I change the email template for mail-creation in gmail to Base64 Content-Transfer-Encoding? Is this possible? Thanks
