Thanks. I just wanted to be sure such a move would not effect (corrupt) what Dovecot was doing (e.g. indexes and such). Glad it won't. That makes things simpler.

Hello everyone, thanks for the fast replies, much appreciated! 2010/5/25 Timo Sirainen : >> I am looking for a command-line utility to automatically purge one >> Maildir folder. > > How about just: > > rm -f /path/to/Maildir/.spam-learn/* > > With v2.0 you can also do: > > doveadm expunge -u username mailbox spam-learn all I run 1.x, so doeveadm doesn't exist. :-) Can I simply delete the files, don't I destroy any indices or slow down Dovecot operation because of index rebuilding? Sounds like a simple solution I also thought of, but I was hesitant of just deleting the files... Thanks, Florian

I would write a script that cron executes, and have the script do the
sa-learn, then delete the file.
I run qmail-toaster, which uses vpopmail for virtual domains/accounts.
My maildirs for learning ham/spam are shared, and are named sa-learn/Ham
and sa-learn/Spam.
Here's the script that I run in cron.daily to execute sa-learn:
#!/bin/sh
#
# learn and remove spam and ham in shared folders
#
# shubes 3/26/08 - created
#
learndir="/home/vpopmail/domains/shubes.net/sa-learn"
hambox=.Ham
spambox=.Spam
do_the_learning(){
learnas=$1
maildir=$2
shopt -s extglob
for spamfile in `find $maildir/+(cur|new)/* 2>/dev/null`; do
sudo -u vpopmail -H sa-learn --$learnas $spamfile
rc=$?
if [ $? != "0" ]; then
echo "sa-learn failed, rc=$rc, spamfile=$spamfile"
exit $rc
fi
rm $spamfile
done
}
do_the_learning ham "$learndir/$hambox"
do_the_learning spam "$learndir/$spambox"
exit 0
# end of script
HTH.
