       dbmail-export - export a mailbox from the DBMail mailsystem to mbox


       dbmail-export [-dDr] [-u user] [-m mailbox] [-s imap search] [-o
       outfile|-b basedir] [-f configFile]


       The dbmail-export program allows you to export a DBMail mailbox to an
       mbox formatted mailbox.


       -u user
          specify the owner of the mailbox you want to export, using wildcards
          ? and * to match one or none, or one or more characters in the
          username, respectively.

       -m mailbox
          specify the mailbox you want to export.

       -o outfile
          specify the file into which the exported mail will be saved.

       -b basedir
          specify the base directory into which the exported mailboxes will be

       -s search
          use an IMAP SEARCH string to select messages (default: 1:*) for
          example, to export all messages received in May, use: "1:* SINCE
          1-May-2007 BEFORE 1-Jun-2007"

          flag exported messages as \\Deleted (use dbmail-util to expunge).

          set delete status on exported messages (user dbmail-util to purge).

          export mailboxes recursively (default: true unless -m option also


       -f configfile
          Specify an alternate config file. The utilities are currently
          hardcoded to use /etc/dbmail.conf for their configs, and will halt
          if the config file cannot be found. Use the -f configfile option to
          specify your system’s preferred config file location.

          Quietly skip interactive prompts and helpful status messages which
          would otherwise be printed to stdout. Use two -q’s to silence errors
          which would otherwise be printed to stderr.

          Operate verbosely. Some of the utilities in the DBMail suite can
          take two -v’s for extra verbosity. Those which don’t understand this
          convention won’t complain about having the extra -v and will simply
          operate at their normal verbosity.

          Show the version and copyright, then exit.

       To export and delete all messages belonging to user Joe in mailbox
       Inbox more than 30 days old, try this command:

          dbmail-export -u joe -m inbox -o joesinbox.mbox -d -s "1:* BEFORE ‘date ’+%e-%b-%Y’ -d ’30 days ago’‘"

       Note the careful bash quoting and backticks calling the GNU date(1)
       command. GNU date(1) has excellent features for retrieving relative
       dates. If you are using a different shell, you may need different
       quotes. Descriptions of relative dates are not supported by BSD

       To export all mailboxes named Spam for all users into individual
       directories following the pattern SpamDump/<username>/Spam, try this

          dbmail-export -u \* -m Spam -b SpamDump

       Note the backslash to prevent the shell from expanding the , as we want
       that  to be passed into DBMail for expansion based on the internal user
