Thanks Jan. My IMAP server reports the message structure correctly. I  
needed to enable the Mailbox Display preference for indicating whether  
attachments exist in a message. In retrospect this makes sense if one  
fully understands MIME multipart, but otherwise it's not very intuitive.

For reference: I found the solution by tracing the matching of System  
Flags until I ultimately discovered that the 'atc_flag' preference is  
required to enable extraction of the Content-Type header from each  
message in the Mailbox.
