I'll have a look into it mate. I currently run my mail on the mailserver of my own server, and collect them via IMAP in Outlook, and until now I've been absolutely spamless. Its a nightmare! lol.
I think I've kicked it into touch, using spamassassin, outlook filters and my internet security built in spam settings which I've now all trained... Not got one yet, and was getting 1-2 a min all afternoon so done something right.
I'll check google mail though.
