  - 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 WIO Mail only sends text
   without any attachment or other part to indicate that a client is active or inactive.
- Confirmed on my vm testbed
