I have Drupal site which is up and running and I've installed a module called 'Comment Notify' to automatically notify users that their comments have been approved. Problem is my outgoing messages don't send and when I look at '/admin/reports/dblog' it says there was an error in sending. Iv'e tried to bypass the Drupal system by setting up a Gmail and sending over SMTP but they still won't send. Anyone have any ideas why this might be occurring?
