Not receiving emails (but MX properly configured... I think)

Not receiving emails (but MX properly configured... I think)

Hi,

With my brand new test domain "lideln.fr" (and my email lideln at lideln.fr) I can properly send email, but I cannot receive them.

I checked the DNS propagation with mxtoolbox, and they seem fine. Please tell me what I should do to fix that issue?

Thanks a lot in advance!

Best regards,
