I consider it spam because it is the same email from a different address every time. Its always got a about 1 sentence and a link to a site selling vigara or something. I started getting these on top of the various other spam and I wondered if anyone else had experienced it start.
I would call that junk mail rather than spam. Junk mail you can control, but not spam. Spam is the real problem for email software.
I get a lot of my junk mail in my yahoo account as well, and when i want to boost my security i get a lot of my messages blocked.
I am also getting massive yahoo mails and also in google and I wonder why I am getting those even in my inbox??..Sometimes I got irritated because I have miss some important mails because of it
