warn recipient if Maximum decoding depth exceeds

[Mathias Zimmermann]

Hi

I configured that if an attachment from a mail exceeds its decoding depth goes to the quarantine with:

$final_destiny_by_ccat{+CC_UNCHECKED} = D_DISCARD;
$quarantine_to_maps_by_ccat{+CC_UNCHECKED} = ['banned-quarantine'];
$quarantine_method_by_ccat{+CC_UNCHECKED} = $banned_files_quarantine_method;

But the recipient don't get a notification., how can I achieve this?

Thanks in advance.

Cheers,
Mathias
