Feedback from x-resend-cc-encrypt-only ambiguous
The following command may yield the following reply when one of the recipient's keys is missing from the list keyring (or I assume under other conditions):
x-resend-cc-encrypted-only: firstname.lastname@example.org email@example.com
Error: Resending to <firstname.lastname@example.org> failed (0 keys found and unencrypted sending disallowed)
The reply does not make it clear whether the mail was delivered to the second recipient or not. This is important to know because it can be annoying for the recipients to receive duplicate mails. I think success as well as failure should be explicitly reported by schleuder in these cases.
