Notification mails aren´t received

[SalvadorS]

Hello,

I don´t receive any notification mails (Under tools -> Panel -> Notifications) Plesk 11.0.9 Update 41

I set administration email or custom email to receive when a client or reseller or domain is created but I don´t receive any mails.

Of course mail under the server works fine. I never receive the mails since we installed Plesk 11 (was a fresh installation)

Any ideas?

Thanks
