I don't even like that.  There are two possibilities:

1) The original message was malware, in which case the recipient can very
reasonably say "Why are you bothering me with this garbage?"

2) The original message was legit, in which case the recipient can very
reasonably say "Why are you interfering with my email?"

I prefer action_bounce so the *sender* knows it wasn't delivered and why,
and can take remedial action without involving the recipient.  Something
like:

        action_bounce($ctx, "Attachments of type .exe are not accepted; please arrange for an alternate way to deliver the attachment, or wrap it in a zip file");

(or whatever policy one might suggest.)
