I activated email routing on my domain, but I can’t seem to get it working.
All DNS options are in place.
I always get the following error message when sending an email:
521 5.3.0 Upstream error, please check Postmaster · Cloudflare Email Routing docs for possible reasons why. hOJAbsbtYEqJ
I followed the steps in the documentation. I don’t understand why it doesn’t work
Are you able to provide a screenshot of the error?
Can you provide the sending and receiving email address?
thank for your support.
I tried to send an email from Gmail to an address @tiresprices.net (my domain)
The response from the remote server is:
521 5.3.0 Upstream error, please check
https://developers.cloudflare.com/email-routing/postmaster for possible reasons why. gsHUTohGG7Ft
I am also experiencing this issue. I have had the route in place for months, but it hasn’t been working for days. I had to change the address it forwarded to from gmail to my old college email and it started working again, otherwise it bounces with that
Any insight here?
