Email Not Working
 

One of my members reported that they could not login,and that when they tried to reset the password, they never get an email. I tried resetting the password from the admin control panel, and I checked Email the new password to the user, but they never got the email, and the password never reset. I even tried making a test account, and tried resetting the password on that account, but I never get the email, and it is not in the junk folder. Does anyone know what is wrong?
