Email notifications error

Not sure how many people noticed this, but since 30th April there has been an error with the email system.

It has not been sending emails for notifications of Private Messages, Mass Emails (sent by us to update people of whats going on), or Verification emails for new members - therefore no new members have been able to sign up since this date. A 'reminder' verification email has now been sent out so hopefully these new members will now see they can activate their account and get on WM, however if you know someone that was struggling to sign up please can you also tell them to do so now as they should have an email waiting for them in their inbox.

Thanks
