   I've had partial success getting BACKUP to store a saveset to a
   mailbox device, but it seems the blocksize is not trivial (first
   tried matching the default /blocksize to the mailbox size).

   Getting data from a mailbox into zip is something that would probably
   be trivial, maybe I'll find time to look into it on my home cluster.

   I forget which version of VMS you had, should I assume you don't
   have create/mailbox?
