• Thunderbird and Roundcube mail clients presume that any mail with Content Type of multipart/mixed has an attachment included rather than actually checking for disposition attachment. This means that any mail with multipart/mixed gets the attachment icon marked up even though there is no attachment.
• Although this is a problem of the clients involved, in this case the simplest solution is to change multipart/mixed to multipart/alternative as the Mail Service test mail only sends text without any attachment or other part.
• Confirmed on my vm testbed
