more than 1 year ago i've got almost the same questions, when had to migrate
from netscape messaging server.
as i found no answers, so decide to do work by myself.
first of all, i wrote a small program on C to parse LDIF from netscape'
exported user database.
things got exported: mailboxes, quotas, aliases, forwarders, passwords in
(yeah) SHA-1 standard.
next thing: i found a way to create password hashes in SHA-1.
as we have only one mail domain serviced by netscape there no support for
but it shouldnt be too hard to add such support.
mailboxes created leaved empty, all their contents leaved on old server, so
users had to download their emails manually.
if you are interested i can send you that my old work

Subject: [vchkpw] Moving from Netscape Mail server to Qmail+Vpopmail?
