As I understand that, that's specifically for messages that originated 
within Exchange itself and had no SMTP transmission or RFC5321 or 5322 
components in the first place. This dates back to Exchange's history, at 
which point it wasn't primarily a SMTP server, SMTP was just one 
possible transport.

Modern Exchange shouldn't be creating this mess anymore, but that 
doesn't help you fix existing messages. SpamAssassin probably wouldn't 
see these messages anyway since, as you described, they're only created 
when you export messages from Exchange to IMAP.

If Exchange sends the message via SMTP, or exposes it via IMAP, it 
constructs something more standards compliant, it's only when you export 
directly from Outlook that you get this mess.
