A significant potion of emails to my domain have the status "Delivery Failed"

Hi there, my issue is that my previously well-running email forwarding seems to break in recent days. Is it because of Gmail introduces new requirements to fight spam? Will Cloudflare do (or be able to do) anything to resume the stability of this service?

It seems that a lot of us using the Email Routing feature from Cloudflare with a free Gmail account are experiencing issues. I’ve implemented all good practices (SPF, DKIM, DMARC, MTA-STS, TLS-RPT records…) and still facing the error (421): 4.7.0. Incoming emails are rejected due to sender’s (mine, because of the forwarding) domain low reputation. As I can see many of us are experiencing this issue, I’d say Google doesn’t like Cloudflare’s IP or something like that.

Funny thing is that not all my incoming emails are rejected, just some of them, what is kind of puzzling, right?

Closing this topic in favor of the current active topic on the matter of Gmail delivery.
