Hi all,
I found the same bug that Jerome Schell reported some days ago about
LDAP per recipient.
Looking at the sources in 2.3.3, in line 5293:
if (!exists($banned_rules{$n})) {
do_log(2,"INFO: unknown banned table name $n,
recip=$recip");
} elsif (!defined($banned_rules{$n})) { # ignore undef
} else { push(@names,$n) }
The !defined is always true, I don't know why...so I commented out.
But appears that the code after line 5366 isn't correct, because isn't
checking agaisnt the rules, apparently is cheking against the key, and
it always return true, and all emails are blocked.

My amavisd.conf

%banned_rules = ('DEFAULT' => $banned_filename_re);
$banned_filename_re = new_RE(
# block certain double extensions anywhere in the base name
qr'\.[^./]*\.(exe|vbs|pif|scr|bat|cmd|com|dll)$'i
);
Kind regards,
