Mail not working anymore here, too

[r.dorsaneo]

Hello guys,
after switching to Cloudflare we cannot send/receive mails anymore.
I have already checked the turorial of domjh:
https://community.cloudflare.com/t/troubleshooting-email-delivery-issues-when-using-Cloudflare/60720
and everything looks fine for me.
Here are my Cloudflare settings:

So, anybody has an idea, what’s going wrong?

Thanks in advance
Rico

Emails should reach your server just fine. The question is if you can access them from your client.

What exactly does that mean?

Post screenshots of whatever error you get.

That is not an error related to Cloudflare. Your mail server simply rejects that email as it does not recognise the user.
