I've been running the experiments in my own account, working from a spam sample that I'd saved off from a place where I've been collecting incoming spam. But these tests really don't have anything to do with local_prefs, because the actual handling of spam mails is done in the procmailrc file. In a system-wide configuration the common procmail handling could live in /etc/procmailrc. Basically, I was just experimenting with seeing how well SA can do when it is fed only part of a large message. The answer is that it does real well, if fed part of both the beginning of the message, and the end - but it doesn't do that well if only fed the beginning of the message, which is currently the behavior of "spamc -s msg_size". I just ran a test using a 2000 byte limit on message size: If the message size is over 2000, concatenate the first 1000 bytes to the last 1000 bytes and feed that to SA. This turned out to generate a small number of unexpected false negatives. To be exact, the baseline case had 399 false negatives (due to using only local rules and no auto-white-listing), but by truncating to 2000 byte messages we generated 7 additional falso negatives. That number, 7 out of 1545, isn't huge, but is noticeable. I dislike it when any spam sneaks through. Not giving up, I'm going to try using the first third, middle third, and last third, and see how it goes. :). ------------------------------------------------------- This SF.net email is sponsored by: ObjectStore.
