What this guide will give you:

• A working KMail configuration for scanning and retraining spamfilter with POP3 accounts (IMAP is not supported because mail doesn't really get "downloaded").
• A DSPAM 3.6.x using the hash_drv, with training data stored in the user's homedir (~/.dspam)

Requirements:

• KMail (of course)
• A sane build environment (gcc and co)
• Superuser access (for DSPAM installation)

Note: this guide has been tested on a full KDE 3.4.1 build on Gentoo 2005.1, so if you have another version, things might differ a bit (in which case you should let us know so we can add it here).
