"You have received an ecard greeting"

I am receiving about 30-40 of these emails a day. Some even show me as the sender. My ISP hosts my email and it’s POP3 (kinda like yahoo or hotmail), so there’s no email filtering at that level. I know these are spam and the links will send you to a bogus website and install a virus. My only question is, since I am receiving so many a day is there anything that can be done to stop them? I have setup a rule in Outlook to move them to the junk folder, but I also get them on my blackberry where I have no way of filtering them out.
