Agreed on all points with Gerd.

True again.
Incidentally, it is possible to build dynamic rules in Amavis::Custom
if need arises (but the given topic does not need such a solution).
Here is an example (the rules are just made up for the example,
not necessarily meaningful):
sub new {
my($class,$conn,$msginfo) = @_;
my($self) = bless {}, $class;
$banned_rules{'RULES-ONE'} =
Amavis::Lookup::RE->new( qr'^\.(exe-ms)$' );
$banned_rules{'RULES-TWO'} =
Amavis::Lookup::RE->new( [qr'^' => 0] );
$banned_rules{'RULES-THREE'} =
Amavis::Lookup::RE->new( qr'.\.(vbs|pif|scr|bat)$'i, [qr'^\.exe$' => 0] );
$policy_bank{'DYNAMIC_BANNED'} = {
banned_filename_maps => [ {
'us...@example.com' => 'RULES-ONE',
'.example.org' => 'RULES-THREE,RULES-ONE,DEFAULT',
'.example.net' => 'RULES-TWO',
'.' => 'DEFAULT',
} ],
};
Amavis::load_policy_bank('DYNAMIC_BANNED');
}
