I generally like to stick to a 1/4 tag/quarantine combination for my spamassassin configuration. It catches the obvious spam that way, and suspect spam is almost always tagged for my review. It also helps to add certain well known spam domains to your blacklist (see: yahoo, hotmail, gmail, other free email providers), then whitelist specific addresses from those providers as needed. This because, in my experience anyway, 95% of spam coes from a fake yahoo/hotmail/gmail address, or an address they registered specificly for spamming, and that's the only sure fire way to stop it completely from sites like this. That in combination with the emails you get letting you know what junkmail you've currently got sitting in quarantine should make sure you catch most/all the crap email, while at the same time preventing you from missing the legitimate ones.
Yes, I have an opinion.
