pereplex on "[Plugin: Contact Form 7] Contact form 7 not working"

Hi everybody.
I've got also the same problem. email can be sent from the website when somebody write something into the blog but nothing if it come from the contact form 7.
I've also checked the FAQ...
I'm also using wordpress 3.5.1
destination address xxxxx(at)hotmail.com no spam filter selected, nothing in the spam.
Best regards, thank you for your help.
