I was getting these a while ago, no subject, no content, can't delete them. They stopped, but today I have received another, the first ones were on a laptop and this new one is on the iPad, any ideas please.
That particular date is the default date stamp indicated when the motherboard battery has reached the end of it battery life, but as Mark says, it may also indicate that the battery on the server has a failed battery. This would also give the incorrect date stamping of the email
