Hi

I've enabled the junk mail filtering into the junk folder by renaming the dovecot.sieve file. It seems to be working but not all of the junk is being filtered. All junk is being flagged with ***SPAM*** in the subject, but only some of the junk goes into the junk folder.

Here's the bit I've edited in my amavisd.conf file:

$sa_tag_level_deflt  = -100;  # add spam info headers if at, or above that level
$sa_tag2_level_deflt = 5;  # add 'spam detected' headers at that level
$sa_kill_level_deflt = 5;  # triggers spam evasive actions (e.g. blocks mail)
$sa_dsn_cutoff_level = 8;   # spam level beyond which a DSN is not sent
$sa_crediblefrom_dsn_cutoff_level = 18; # likewise, but for a likely valid From
# $sa_quarantine_cutoff_level = 25; # spam level beyond which quarantine is off
$penpals_bonus_score = 8;    # (no effect without a @storage_sql_dsn database)
$penpals_threshold_high = $sa_kill_level_deflt;  # don't waste time on hi spam
$bounce_killer_score = 100;  # spam score points to add for joe-jobbed bounces

This is the header from an email that *did* get moved to the junk folder:

Any ideas?
