I recently was able to receive emails on my domain but since today I cannot receive emails anymore, but I can send emails.
I’ve put the MX record to mx.epizy.com on Cloudflare as shown on the picture below.
Do you know anything else about the failed emails? Did your mail server send you an email back with an error message (called bounce email)? Which provider or providers did you try to send it from?
I’ve been told that these bounce messages were accidentally sent as a consequence of fixing another issue in the mail server. In any case, the bounces are all done and incoming email should work again.
