To do the best possible job of catching spam, SpamBayes needs to be well-trained. This means letting it know what you think is spam and what you think is ham (not spam). If you're using the Outlook plug-in, training it is simply a matter of using the "Spam" or "Not Spam" button whenever it fails to classify something correctly.
 
Once SpamBayes is well-trained, you may find it useful to alter the cutoffs for "Possible Spam" and/or "Certain Spam." In particular, if you find that you frequently get messages that are somewhat below the cutoff for "Certain Spam" and that such messages are never ham, you can lower that cutoff. It's set fairly high by default to avoid incorrectly classifying ham as spam. (In the absurd extreme case, you'd set it so low that all messages were classified as spam. This literally satisfies your request to "catch the most spam," at the cost of treating your ham as spam as well, which I doubt is what you want.) If you're using the Outlook plug-in, you can adjust the thresholds for Possible Spam and Certain Spam on the Filtering tab of the SpamBayes Manager. Click the SpamBayes button on the Outlook toolbar, select SpamBayes Manager... from the menu that pops up, and click the Filtering tab.
 
There are lots of obscure settings that you can mess with, but unless you really know what you're doing, you're unlikely to improve the classification; the defaults are well-chosen.
