Subject: 26.3; Sending Mail to Recipient without public key
Date: Tue, 10 Mar 2020 10:27:57 +0100

I configured to encrypt all outgoing mail via customize. When I try to
send an email to a recipient, from which I don't have a public key, I'm
getting asked, if I wan't to skip it. If I confirm, I'm getting the
error-message: mml-secure-recipients: No recipient specified. My
expectation would have been, that I send the mail unencrypted.

If I have multiple multiple recipients and I don't have the key from one
of them, I'm getting asked again wether I want to skip the recipient. If
I accept, he gets a weird message with the following contents:

Attachment: [1. application/pgp-encrypted]...

[[PGP Encrypted Part:Failed]]
[1. application/pgp-encrypted]...

[[End of PGP Encrypted Part]]



The other recipients get a normal encrypted email.

I think that sounds like expected behaviour -- if you've told Emacs that
all mail should be encrypted, then Emacs will refuse to send unencrypted
mail, I think.

So I think this works as designed, and I'm closing this bug report.
