Sorry for posting on both list spamassassin and dovecot : my question is
on dovecot antispam plugin, used to learn spamassassin with sa-learn.
I wonder if there is a way to confirme sa-learn is correctly feeded by
the antispam plugin.
using that script to pipe message to sa-learn :
#!/bin/sh
echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt ;
echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log ;
#echo $* > /tmp/sendmail-parms.txt ;
cat<&0 >> /tmp/sendmail-msg-$$.txt ;
/usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt ;
rm -f /tmp/sendmail-msg-$$.txt ;
echo "$$-end" >> /tmp/sa-learn-pipe.log ;
exit 0;
above script is missing important log information: the current uid and
$HOME; also sa-learn knows -D
I would change for a testing period:
#!/bin/sh
echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt ;
echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log ;
#echo $* > /tmp/sendmail-parms.txt ;
cat<&0 >> /tmp/sendmail-msg-$$.txt ;
/usr/bin/sa-learn -D $* /tmp/sendmail-msg-$$.txt >/tmp/sa-learn-pipe.$$.tmp
2>&1;
echo $$ sa-learn rc=$? id=$(id) HOME=$HOME >> /tmp/sa-learn-pipe.log
while read line; do
echo $$-sa-learn "$line" >> /tmp/sa-learn-pipe.log
done < /tmp/sa-learn-pipe.$$.tmp
rm -f /tmp/sendmail-msg-$$.txt /tmp/sa-learn-pipe.$$.tmp
echo "$$-end" >> /tmp/sa-learn-pipe.log ;
exit 0;
For me, it's working, but when i run sa-learn --backup, i just get
this :
v 3 db_version # this must be the first line!!!
v 0 num_spam
v 0 num_nonspam
Read man sa-learn section MIGRATION: "Note that if you have individual
user databases you will have to perform a similar procedure for each
one of them."
sa-learn --backup > backup.txt
backups the database of one particular user, I assume you use root to
issue the command? But is the antispam learning script above runs as root,
too?
I assume you need some --username=username and/or --prefspath=file
setting.
