At this point (as others have said) you need a new address. Spam filters will help, and as others said, they spammers constantly change the send address, filtering that will provide almost no relief.
I've mentioned this before, and I didn't believe it at first, but it is true and it helps:
Just opening an email can verify to the sender that you are a valid email address and a 'real live' person. With that information, I think your email address becomes 'hot property' and gets sold to a gadzillion other spammers.
What to do: Disable any sort of 'automatic preview' of images in emails.
How this works: The bad guys send a billion emails out with embedded images. Those images are displayed by linking to the image on their web server. Every email gets a different randomly generated number attached to that image, and they keep a database of image #'s versus email addresses. So when their site gets a request from that number, they know you actually opened the email. You have just become a target. Did you see the laser beam on your forehead?
So disable previewing. Now.
Oh, the other thing - do people forward you jokes, or political 'hot-button' stuff, or heart-rendering stories, and such and they get forwarded? Unless they did a 'blind CC'; your email address is on that list. Spammers intercept them along the way, and there you are.
If anyone forwards me one of those, 'IMPORTANT: forward to everyone you know', they get an earful from me, and I make 'em clean the cobwebs out of my attic and scrub my septic tank until it shines, while I pour molasses and red ants on them, stick ear-buds in 'em playing 'Honey' by Bobby Goldsboro non-stop. Haven't gotten one in years.
It doesn't make any difference that YOU didn't forward it - other people are forwarding it and it has your address on it. That's all it takes.
