Drupal is not sending emails out to any of the users.
I noticed the problem when a visitor registers as a new user they are able to complete the process but the system is unable to send an email to the new user for them to login.
I am also receiving errors in my log files when I try and send Webforms.
I have attaced an image of the message that appears :
I was using the default email program and I installed the SMTP module with no change.
My site is located on Godaddy and I called them and they said the problem is with my installation.
The system is:
Drupal Version: 7.16
What I need is someone to solve the problem with my site so that it sends email.
They should make available with a minimum of documentation on how the problem was solved.
