Signed or encrypted messages do not have a signature/disclaimer appended

Scenario:

You are using Exclaimer Cloud. When a signed or encrypted message is processed, no signature will be appended.

-or-

You are using Exclaimer Mail Disclaimers / Exclaimer Signature Manager Exchange Edition. When a signed or encrypted message is processed, no signature is appended but the original message is added as an attachment to a wrapper message. A plain text signature/disclaimer is appended to the wrapper message.

Reason:

This is expected behaviour. It ensures that security on the message is preserved and un-tampered with when the message is delivered to the intended recipient.
