OK, my bad re: gpgsm; I didn't grok the limits of that tool.  So strike
the "anything else" and replace it with "Outlook".  From my mucking
about:

- Clients:
  - gnus-article-mode and descendents
  - TBird
  - Outlook
  - OpenSSL smime
  - gpgsm [with p7s/p7m mime-part properly extracted]

- Signed only messages validate with all clients

- Encrypted only messages decrypt with all clients

- Sign+encrypt messages fail with Outlook.


Outlook is completely unhelpful here; with debug enabled via `defaults
write com.microsoft.Outlook LogForTroubleshooting -bool TRUE` on macOS,
this is about all I can find that's relevant:
