Replying to myself here -- I got it working :)

I would like to understand why I had trouble to make it work, so am I=20
right in the following assumptions:

It seems that setting=20
$viruses_that_fake_sender_re/@viruses_that_fake_sender_maps to undef=20
was a bad idea. This seems to set the variables to the default built-in=20
values instead of empty as I would like it.

Another thing is that is seems that only "new-style" variable (*_maps)=20
can be overridden with a policy_bank. "old-style" variables makes the=20
policy_bank issue a warning in the log and the not modify anything.

My config is now:

$final_virus_destiny =3D D_DISCARD;
$final_banned_destiny =3D D_DISCARD;
$warnvirusrecip =3D 1;
$warnbannedrecip =3D 1;
$viruses_that_fake_sender_re =3D new_RE();
@viruses_that_fake_sender_maps =3D ();
=2E..
@mynetworks =3D qw( 127.0.0.0/24 );
=2E..
$policy_bank{'MYUSERS'} =3D { # mail from authenticated users on this=20
system
# Bounce only to local users
final_virus_destiny =3D> D_BOUNCE,
final_banned_destiny =3D> D_BOUNCE,
warnvirusrecip_maps =3D> undef, # (defaults to false (undef))
warnbannedrecip_maps =3D> undef,# (defaults to false (undef))
warnvirussender =3D> 1,
warnbannedsender =3D> 1,
mynetworks =3D> qw(0.0.0.0/0),
};
