If these attachments do not have a Content-Disposition filename=
field, this would appear correct.

I can confirm this behaviour with dtmail under Solaris 7.
For instance, a recent message sent to mutt-dev with the structure
I 1 <no description> [multipa/mixed, 7bit, 1.6K]
I 2 |-><no description> [text/plain, quoted, us-ascii, 0.6K]
A 3 `->TODO.diff [text/plain, quoted, us-ascii, 0.7K]
I 4 <no description> [applica/pgp-signat, 7bit, 0.2K]
appears in dtmail with an empty message field and three NoName
attachments. So, I'd say that dtmail has certain problems with
multipart/mixed. Attachment 3 _is_ named
Content-Disposition: attachment; filename="TODO.diff"
and dtmail doesn't recognise this.
