As I posted a few days ago, I am also being inundated with spam. I am getting maybe 50-100 a day !
Some of them are going into my spam folder but at least a third are going into my inbox. As soon as I see them, I define them as spam, but they still keep coming, so I am beginning to think that the spam facility isn't working properly.
I mail provider is BT Yahoo, so I am going to have a ferret around today, to see if anybody else is suffering. This has been going on for about 2 weeks.
