hmmm, must be some new POP protocol that hasn't been made a standard yet
then :-)

I have a feeling you wasted a ton of bandwidth doing this, as mailfilter
has to download the mail to be able to properly filter it and then if it
thinks it is spam marks the message(s) for deletion on the server.

After that, KMail connects to the POP server and re-downloads the
messages again (except for the deleted ones of course).

echo "spamassassin -e" > ~/bin/spam-filter.sh
chmod +x ~/bin/spam-filter.sh

Then, in the Evolution filter editor, add a new filter and make your UI
match my very skillful ascii-art.

Rule name: [Spam                          ]

If
[Pipe Message to Shell Command][/home/<user>/bin/spam-filter.sh][returns
greater than][1]

Then
[Move to Folder]["Spam" in "Local Folders"]

And then hit OK and as if by magic, you now have a spam filter.
