I've had a perfect storm of email nonsense. Since moving servers I had a stack of errors saying internal replies to threads could not be delivered even though they were and after upgrading to 1.5, nothing is reaching my hosts. New registers confirmation emails are not reaching new users, Contact Us doesn't work and replies to thread notification to members are not being sent either (or at least not reaching them). I've literally spent hours on this and cannot resolve it. Anyone have any ideas? PS. Go easy with the tech speak please, absolute newbie here - thanks!
