From time to time I receive an email from someone (not necessarily the same
person) telling me that a message from me was deleted on such and such a
date. The subject is *Not read: the original subject*.

I don't always recognise sending the original message in the first place and
I don't see why I should be notified of the fact that it has been deleted
from the recipient's computer. Is this virus-related or does it happen to
everyone?

Thanks
