The Eudoras I've used (versions 1 through 3) do not leave "attachments"
inside a message body. Each attachment is "detached" into a separate file
and replaced by a line in the body "Attachment converted: filepathname".
There is no trace left of the MIME content type. Thus to show an attached
graphic MHonArc would have to track down the "detached" file, then examine
its contents, to discover what the content type should be. On Windows 95/NT
platforms a registry query should be able to map a file extension to a MIME
type.
I believe that Eudora 1-3 used little more than "application/octet-stream"
for attachments. (It does distinguish text from binary attachments.)
Eudora 4 introduced support for HTML-format message and may handle embedded
images differently from attached ones.
It would seem that MHonArc would have to do some heavy platform-specific
processing to handle attached files associated with Eudora V1-3 mailboxes.
