Greetings - some warez company keeps spamming me and I don't know how to filter it out other than by some hit and miss subject line key words, but I'd rather not go that route because I might inadvertently filter out non-spam mail as well.

Rather, I'd like to target my filtering elsewhere, but since the FROM line always changes, I'm looking at some of this header info for answers. Unfortunately, I don't know what if any of this info might help me create an effective filter.
Thanks in advance for suggestions:
