Crazy - Out of Control SPAM Again

For a short time not too bad in the SPAM department. Once again it is out of control daily going directly to my In Box Folder not to mention my good mail going to the SPAM Box Folder. I use Yahoo to access another account and Yahoo does a much better job filtering and I don't have to set up all this stuff for it to recognize it as SPAM like we have to do with Cox. Cox...please work on this ongoing issue. LOL...I don't think they really care. Thank you.
