Assuming the mbox is a normal mailbox file you could use an IMAP client
that knows about proxy authorization: authenticate as an IMAP admin 
(cyrus) and authorize as the user in question, so you could perform all
transfer operations under the user privileges.
  I know at some point on the list somebody suggested using mbxcopy from
imapd-tools (UW tools, requires c-client from their site also).
mboxcopy knows about proxy authorization and trasfers from any format
c-client understands (mbox, pop3, imap) to other format.
  I have been using it (a modified version which included the cyrus 
password) to backup the imap mailboxes to regular flat mbox format.
  I don't recall if somebody on the list posted or just said that
he patched mboxcopy to get the admin password via an environment 
variable rather than hardcodeit into the program (like I did).

  I must admin it sounds simpler than it actually is to implement,
you could just change the password temporarily and restore it
back with the original sasldb2.
