Well, it does run it's tests on each message, but even on dial-up I don't notice a slowdown that I would consider significant. My wife gets hundreds of messages a day, and the download process doesn't irritate her. > > After I quit Kmail, spamd is still running.

I can't figure out how one daemon is slowing a game, unless you are set to download mail automatically when it arrives on your mail server. Maybe you can try setting the client to only download messages when you request it to do so??? Are you running with "procmail" or just with Kmail (the way I do it). I seem to recall that if SA is <pipe through> spamc that it is much faster than spamd, even though spamd must be running for spamc to work. And you have SA called by the Kmail filter system and have it set to not check messages greater than 250KB in size? > > Training.

If the "unknown" message contains dictionary words in html, white on a white background, the message would appear blank. Your system would recognize that the words were there, but you can't see them (spammers are slimey bastards), and unless you have an extensive ham-to-spam Bayes library, the message would probably not be tagged spam. This type of attack only works for a little while, though, because once you have enough messages to get SA trained it will recognize the difference between "hammy" and "spammy" words, and unless the spammer gets really lucky and happens to include enough ham in the dictionary portion of the message it will be flagged spam anyway. > > Thanks!
