As an admin I used to have a smooth working site for a year and suddenly since a week ago all my new users's registerations, posts, comments' notifications and even users don't any more receive email confirmation sendouts. I am now confirming new email addresses manually but this can't last forever.
I have not changed any of the settings of my server or my site for at least a year. Any ideas on why these notifications have stopped?
This is my site.
