A remark on these kludges: an S/MIME email from a colleague elsewhere
using Outlook and their Exchange server was still mangled by our Exchange
server. Sending to their Exchange server (avoiding our Exchange server)
didn't exhibit the same characteristics. I would have hoped that staying
entirely within one vendor's tools really should work.
The trigger in both this case (and the example emails I sent earlier)
appears to be attachments.
Overall, it makes signed emails just so unreliable. But I guess we
already knew that.
