P7M Message (Keychain opens, what next ?)
Hi All,
I'm using Apple's Mail.app. I received an empty email message with smime.p7m attached.
When I double click smime.p7m, Keychain opens and nothing else happens. The message is not opened, there is no message box, there is no error message, nor other prompt telling me what I should do next.
What am I suppoed to do next on Apple's platform using their mail prgram?
Thanks in advance,
Jeff
