TBF, not sure if you are using Outlook/Outlook Express, but setting one or two message rules up will sort the crap out.
I used to get loads, never get any now.
Just been on to Orange (probably the best for letting spam through) home page to view my account, 367 messages in the junk box, and 106 unopened.
So now if i open Outlook i will connect with the Orange server and i might get one or two personal emails the rest stay with Orange and get dumped in the "junk box", and then are deleted after seven days.
Most spam that you get will be a corruption of your email address, EG: big@fi
