I have a (from my point of view) simple setup:

    1. sort out all mailing-lists/newsletter
    2. sort out mail from people I do not want to read
    3. bogofilter
    4. check that no one out of my whitelist is classified as spam
    5. the rest goes into my inbox

You can take a look at the complete setup at
<http://alexander.wasmuth.org/procmail/>. Beware, I am no procmail
expert at all ;)

I extract the addresses from abook to generate a whitelist, known
senders get a X-Whitelist header so that bogofilter is able to
reclassify any false positives. The relevant part:

[...]
:0fw
| bogofilter -uepl

:0e
{ EXITCODE=75 HOST }

:0:
* ^X-Bogosity: Yes
* !^X-Whitelist: Yes
JUNK

:0c
* ^X-Bogosity: Yes
* ^X-Whitelist: Yes
| bogofilter -Snl
[...]

I considered that, but a quick check at my spam-box revealed that in
fact about 70% of the spam contains my address in the TO- or CC-Header.
Anyway, bogofilter is making a very good job so I leave it this way.
