I see that for some messages, but not all messages. For example, I had a 
colleague send me a signed and encrypted S/MIME e-mail so I can add her 
certificate to my keychain.

I see a “Security: Encrypted” header and a “Successfully decrypted 
S/MIME message.” banner, but when I click “Show Details” I get the 
following:

~~~
DECRYPTION_OKAY
------
GOODSIG <REDACTED-USER at REDACTED-DOMAIN>
TRUST_FULLY ...	
~~~

(Redacted e-mail address only; the `...` and the rest are exactly what I 
see.)

And there’s no option to add the certificate to my keychain.

If I do “Quick Look Attachments...” I see a `.p7s` attachment, so 
there is a signature there, but MailMate fails to recognize it.

I’m happy to take this off-list to troubleshoot further, but posted it 
here in case anyone else was seeing the symptoms.
