Email strange problem

[mousik2]

Hi, couple of days ago e-mail was working fine. Today is not working, i can't send email to user, i don't recieve any email when i'm creating a new account. In the contact page when i filled the form and press send button i see MAIL HAS BEEN SENT and address in web browser is like this: /index.php?main_page=contact_us&action=success
When i try to send email from admin panel to user i see on the top of page EMAIL SENT TO: <[email protected]>
So... Did someone had similar problem?
