Forms are not sending mails

Hi,

I have several forms made by Contact form7. But after submitting no reaction on the email I put in ([email protected] or [email protected]). If I put my other email ([email protected]) in the form it works. What is going wrong here?

The correct mail must be [email protected] and this mail is working good if I just send an email to this adres.

Someone knows what to do?
