- $message->{shelved}{smime_sign} & $message->{shelved}{smime_encrypt} attributes are set to indicate signing/encryption are required.
- Messages are checked if encryption is possible on all recipients before they are stored into bulk spool.
- As a side effect, messages sent by robots will be signed if keys are available.

Known issue: This feature won't be applied to the messages stored into bulk spool before upgrading.
