File types are considered in the context of banned checks, which can be 
configured by various banned_* confvars. Generally some confvars are 
global, some are per policybank, but I know only two confvars that can 
make other policybanks be loaded. The banned_* confvars are not one of 
those.

However, if you're really desperate, you can try something like this:

> @banned_filename_maps = sub {
>     my ($msginfo, $recipient) = ($Amavis::MSGINFO, @_);

>     if ($msginfo->sender eq '[email protected]' &&

>     } else {
>         return { '.' => [new_RE(qr/\.(?:com|exe)/)] };
>     }
> };
It yields

No guarantees, though.
