Funnily the spam filter is what finally got me off Gmail. It developed a serious false positive problem with a couple of mailing lists I'm subscribed to - and yes the address was in my address book and all the other usual 'fixes'. I can handle false negatives occasionally, but false positives are much harder to spot. Fastmail's filter (SpamAssassin for the most part) is configurable in how aggressive it is.
