I have added those lines but the results are still the same.
I have also done the 18.104.22.168 update.
I have noted the following:
in ispc I have
SPAM subject tag = ***SPAM 3***
SPAM subject tag2 = ***SPAM 6***
but in /etc/amavisd.conf
$sa_spam_subject_tag = '***SPAM***';
and no entry for tag2
Also, when I save the spamfilter settings in ispc it does not write to /etc/amavisd.conf
