POP3 filtering has to be enabled first: Settings | Configure KMail Network | Receiving Select the account, Modify... X Filter messages if they are greater than [...] The problem with filtering on the server is that KMail has to download the headers of *every* message that is over the specified size. This means that the headers of messages that don't get deleted (ie the good stuff) gets downloaded twice. Since a lot of spam is as small as a kilobyte, this results in a massive duplication of downloading if you set the threshold at something small. If most of your mail is junk this might not be a big deal, but if you're on mailing lists it can slow things down quite a bit. It's probably best to use a local filter instead, and this also allows you to check for false positives anyway. I only use this feature for large (>50kB) messages, most of which are probably viruses. -- David P James Ottawa, Ontario http://david.jamesnet.ca ICQ: #42891899, Jabber: davidpjames@jabber.org If you've lost something, you had to lose it, not loose it.
