Sweep function not working properly.

Have input sender's name, a word or two from the subject, and have also put in block sender's list. Unfortunely, their email addresses change daily. If I go to Web site of every address , which is half a page, the only choice is to unsubscribe which I  won't do.  Some of the subjects have an icon in front of the text and at end of subject, but not all..  How many filters can be put into the sweep function????  The problem has nothing to do with the browsers I use..

I'll gladly send a list of all blocked so far concening this Email plus the headers but can't get those in view source because I only get my address and lots of lines of jibberish...

Please read above carefully
