Some automatic handling driving from Nigel filer set

Following Nigel's how-to and philosophy I am now using "cron" to automatically 
handle bogofilter actions off KMail.

Recall :
. "Spam" folder contains manually handled messages of spam type  ; mainly used 
at the very beginning to start training bogofilter and then each week through 
cron automatic action.
. "NonSpam" folder contains manually handled messages of ham type  ; mainly 
used at the very beginning to start training bogofilter and then each week 
through cron automatic action.
. bogofilter filtering is piping messages to "inbox", "spam" or "unsure" 
folders depending of recognized type (spam, ham or unsure) ; all these folders 
but "inbox" folder have a 30 expiration period.
. it is up to the user to check from time to time :
- content of "inbox" folder to move spam messages not correctly detected to 
"Spam" folder,
- content of "spam" folder to move ham messages not correctly detected to both 
"inbox" and "NonSpam" folders,
- content of "unsure" folder to move spam messages not correctly detected to 
"Spam" folder and ham messages not correctly detected to both "inbox" and 
"NonSpam" folders.

>From there on training of bogofilter on "Spam" and "NonSpam" folders is 
automatically handled through a cron action each week by executing the 
following script (I used Kcron to set this action) called 
"training_bogofilter" :

#!/bin/sh
dir_data=/media/USER1_data/dmoyne_data/Mail_data/KDE_Mail/.Bogofilter.directory
kmail=/usr/lib/kde4/bin/kmail
#a) we train bogofilter on Spam and NonSpam folders
echo "training on Spam mail"
bogofilter -sv -B $dir_data/Spam/cur
echo "training on non-Spam mail"
bogofilter -nv -B $dir_data/NonSpam/cur
#b) we clean Spam and NonSpam folders only if KMail is not running
if [ "$(pidof $kmail)" ]
then
  echo "KMail is running : we do not delete files as this might be 
troublesome";
else
  echo "KMail is not running : we delete content of Spam and NonSpam folders";
  find $dir_data/NonSpam/cur -iname \*.* -exec rm {} \;
  find $dir_data/Spam/cur -iname \*.* -exec rm {} \;
fi
#c) we display some information on bogofilter data base
echo "message count :"
#bogoutil -w ~/.bogofilter .MSG_COUNT
echo "wordlist.db :"
#bogoutil -d ~/.bogofilter/wordlist.db
echo "finished"

Of course variables "dir_data" and "kmail" have to be set according for each 
user's setting.

You can see that in this script though training of bogofilter is all the time 
executed I preferred to delete content of "Spam" and "NonSpam" folders only if 
KMail was not running to avoid some possible conflict ; maybe such precaution 
is not needed but due to the fact that the cron action will be repeated again 
and again I found this appropriate.

So far I have tested the script that works but I will have to wait to say if 
my cron action is properly managed.
Regards.

By the way can you use KDE-4 Kmail client to send signed messages ?
