Getting email from myself after enabling Email Routing

I recently enabled the Email Routing feature. It seems to be working well, except that now I’m getting some emails that appear to be coming from the domain I have in Cloudflare. It has to be spoofed headers, since Cloudflare wouldn’t be sending these, and they’re clearly spam messages.

My question is whether or not there’s any settings I can change to block these. I think I could set up a mailbox rule on the destination mailbox to block anything with “header.from=mydomain.com” in the header, but that’s something I would have to do in each destination mailbox. Is there something I can tweak in Cloudflare that would prevent these messages from relaying at all?
