We have an old backup from an old Groupwise (on Linux) system. This is tar file that contains the post office and domain structures. The tree that this system was part of has long gone.

One of the users would like to recover mail from his old mailbox for audit purposes.

Is it possible to recover data from this backup? If so how do I go about this? I have a new empty OES2 server and tree if this helps.

Many thanks,
