no mail to admin

Hi to every one.
I set up everything so that the inscriptions come administrator joomla , I tried in every way but still does not get any mail to the administrator . Mail out from joomla work perfectly , but do not reach the mail MembershipPro.

Can anyone help me? I'm becoming crazy. thanks

I remember that we communicate via support ticket, so please continue communicate with me via support ticket (after checking IPN History of the Paypal account) so that we can find out the reason from there

Regards,

Tuan
