Would you explain how that shall be avoided?

You send an email to me. You encrypt it to the key which I want you to 
encrypt it to. Then you sign the encrypted data.

If I receive an email from you which is not encrypted and signed (as the 
outer layer) then I go on red alert. Like today I might if the message 
is not encrypted or not signed.

How shall THEY create an encrypted-signed message if you have e.g. sent 
it without encryption? The adversary needs your signing key.
