There is an unbelievable amount of Spam coming through with worrying email addresses - worrying on the one hand because they contain familiar names (but are not genuine), and on the other hand because there are quite a few with obvious pornographic content. Even if I block all the addresses, new ones with the same user name but different domain name come through.

Also, the Spam folder does not even show a number next to it, so unless I check the folder, I don't know that new emails have landed there.
