Summary: S/MIME signing and encrypting seems to be incompatible with multiple From addresses. I can successfully sign and encrypt mails as long as there's only one From address defined in my mail account. As soon as I add another address, iOS Mail complains that it doesn't find a signing or encryption identity. Encryption is still possible in some weird cases but signing never works. Steps to Reproduce: - Create an IMAP + SMTP Mail account with S/MIME signing. - Verify that signing and encryption works correctly. - Add a second From address to the account. - Reboot (just to be sure). Expected Results: Signing and encryption should still work as long as the From address matching the cert is selected. Actual Results: Signing doesn't work (missing signing identity error), no matter what From address is selected. Version: 11.1 Notes:
