i have seen variations on this problem in a number of situations.
even when mounting the sam upas/fs after posting to /srv, faces
and upas/nedmail don't play nicely under drawterm for me. the faces
display properly and reflect the contents of the mailbox, but
clicking on the face yields "message disappeared".

i suspect there is something causing the path to the message to be
malformed or misparsed in the plumbing messages generated by upas/fs.
