Hank here from Shopify.
Thank you for reaching out about the issue you are having with your Hotmail email, and emails being returned to you with the above error.
There is currently a known issue where we are seeing some spam folder placement or bounce back of emails with Microsoft due to some COVID19 related emails being sent through our platform. We are working diligently to address this issue and prevent further issues.
In the meantime, if your customers are experiencing similar issues, please encourage your [Hotmail/Outlook/MSN/etc] recipients to check their spam folders (“Junk Email Folder” for Microsoft users) for your emails and mark the emails as “It’s not junk”. If the mail is not in the spam folder, it’s possible that the email may be caught in a temporary processing delay, or has been deleted by Microsoft if the message is > 10 days old. This action of rescuing emails from the junk folder will significantly help Microsoft’s filtering algorithms learn that this is legitimate mail that should be placed in the inbox.
However, with your example, it looks like the email is being rejected from the Hotmail server. So what I would advise doing is to reach out to them (Hotmail/Microsoft) directly with regard to the message you have, but also if you try to resend the email 2.5 hours after it comes back, some emails are being sent through with success.
While this is not a direct resolution for you, it is something that our Developer Team is working with Microsoft to remove our Sending IPs from their low reputation lists. That being said since this is a manual process I am unable to provide a time expectancy on when this problem will be resolved, and we appreciate your patience and understanding with this.
All the best,
This issue has now been resolved as confirmed by both Microsoft and Shopify developers.
So the emails should not be routed to spam or bouncing for you now. If however, you do experience any issues, can you please reach out to our live support team, who will treat this is an isolated issue.
Thank you for your patience with this!
I'm having this issue. It has nothing to do with COVID emails.
Rather, the shopify notification emails and invoice emails I send to any Charter based internet address always bounce back.
The error I'm getting from Charter is #AU In 1160, "The email you tried to send goes against your domain’s security policies".
This only seems to affect Charter related email addresses.
How do I fix this?
