A user receives a mail. A subject and Body of it are in UTF-8. The subject is readable in Notes client, but Body is not. When I switch Encoding to Unicode (Autodetect) in the client I can read the Body of the mail.
Subject: =?utf-8?B?wqvQktCy0LXQt
Content-Transfer-Encoding: base64
Content-Type: text/plain; charset = “utf-8”
Also it’s not possible to read such mails in WebMail.
