As documented no mail is delivered after Milter failure. The Postfix
SMTP server will reply with an error status code (4xx) and the
client will have to send the message again.
The bad alternative is "milter_default_action = accept", which means
that mail will be delivered but not archived.
If you want both mail delivered AND mail archived, then you need
to use sender_bcc_maps or recipient_bcc_maps to add recipients for
archival purposes.
Then, Postfix will do the retrying until the message is too old,
at which time it will be returned to the sender.
