The plugin doesn't use the CDO API -- it's too problematic across Outlook
variations (e.g., it appears it's not even available in most IMO
configurations, unless the user manually installs CDO from their Office CD).
It uses low-level MAPI instead. Search the source for the MAPI
PR_TRANSPORT_MESSAGE_HEADERS_A property and you'll soon find it. Be warned
that raw MAPI can be extremely painful to work with (although it's a hell of
a lot easier to work with from Python than from C!); OTOH, it's much faster
than CDO too, and that's important to the plugin for high-volume users.

The same module you'll find above, in the SetField method of class

Using MAPI directly appears to sidestep most Outlook whining. At least so
