Not receiving Easysocial registration emails

Hi,
I'm not receiving any emails after any site activity. My Joomla test email is working (SMTP). Also, new user sign up is enabled in Easysocial>Settings>Registration.
My site is hosted in Arvixe, and following is my Cron Job setting -
wget http://www.bloodrequest.org/index.php?option=com_easysocial&task=cron
Cron job is set for every 5 minutes.

Please help me to resolve this issue.

Thanks
Anirban
