Please double check your e-mail settings under System > Global Configuration in Joomla. From what I can see here, you are using PHPMail to send out e-mails and most of the time, these e-mails would land in the spam box due to the credibility of the mail source.

I would suggest that you check with your hosting provider to get a proper SMTP setup.

Thanks Mark, it is ok now.

You are most welcome
