Is it possible to allow certain file types from certain addresses to
certain recipients without knowing the sending IP to add them to a
policy bank?
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 'com-sen...@example.com' &&
$recipient eq 'com-re...@example.org') {
return { '.' => [new_RE(qr/\.exe/)] };
} else {
return { '.' => [new_RE(qr/\.(?:com|exe)/)] };
}
};
It yields
(00739-02) Blocked BANNED (text/plain,.asc,file.com)
{DiscardedInbound,Quarantined}, [127.0.0.1] <sen...@example.com> ->

No guarantees, though.
