Python interface to Groupwise mailoxes?

[S. Blakey]

Is there an existing python interface to Novell'sGroupwise mailboxes?
The excellent library reference mentions the mailbox module (section
12.18) which provides access to many standard mbox formats, but I see no
reference to this one.
Failing an existing python module, are there ANY open-source programs that
interface with Groupwise that I can use as a starting point to build such
a module?  Even some good documentation of Novell's proprietary crap would
appreciated.
