First check if .exe extension is not commented out in
$banned_filename_re definition, then check that 'zip' is not commented
out in @decoders definition in your amavisd.conf. This is enough.
"Filename banning" is in fact a misnomer because when you switch on
banning files with .exe extension, the file content is also checked, so
if an executable has for example a .pdf extension, it will be banned.
