I am running Spamassassin 3.0.2 and Fetchmail 6.2.5 on Xandros, which is similar to Debian "Sarge".
I followed the directions in the Spamassassin wiki at http://wiki.apache.org/spamassassin/SingleUserUnixInstall under the section "Enable IMAP LearnAsSpam folder". The problem is that no matter how I specify the IMAP folder, as "LearnAsSpam" (without quotes), "Maildir/.LearnAsSpam" etc, fetchmail is unable to find the IMAP folder. I am using kmail to create the folder and no matter where I put the folder, fetchmail cannot find it. Has anyone done this successfully with kmail? I also have Thunderbird and I could use that. thanks 8)
