If it helps .... here are my current Filter Rules (so far). Since having them in place I've gone from 1 to 2 spam emails per HOUR in inbox, on some days, to none.
Not all added at once. I'm sure the odd one of the filters might contain legitimate companies, but if it stops getting crap from numpkin-heads that use legit ISP's, then so be it. I've found nothing I've sent to the SPAM bin so far that I shouldn't have sent, or would have wanted to keep. Everything now goes off to SpamCop.

Good luck and hopefully I've not broke any forum rules .... if I have .... copy 'em fast before they get deleted 😉
