Spam filters use a number of rules to determine a message's status. The one we use has about 20,000 rules against which to check. rule-hits are assigned a number of "points"; if a message has multiple rule-hits, the points are added up to a total score; if the score exceeds a certain value, it is considered spam, and thrown in the junk pile.
typically, no single attribute will automatically cause a single message to be flagged as "spam".
the attributes could be a particular server address or domain, or the contents of the various fields in the message header, or the way the sending server communicated its message...all kinds of stuff. They all do things a little bit differently, with some filters being more aggressive than others. only way to tell exactly why a particular message was blocked is to see a log file (if one exists) that explains what the filter "saw".
our filter keeps everything it blocks for a period of time, to allow users to manually confirm their validity. There will never be a "perfect" mail filter...there's always going to be stuff caught in error, and junk allowed through, because it is a cat-n-mouse game that the spammers and filterers play with each other, each always trying to out do the other.
