  2. # Example script for removing a Maildir from a Courier-IMAP virtual mail
  3. # hierarchy.
  4. # The script looks at arguments 1 and 2, assuming that they
  5. # indicate username and domain, respectively.
  6. # The script will not actually delete the maildir. I moves it
  7. # to a special directory which may once in a while be cleaned up
  8. # by the system administrator.
  9. # This script should be run as the user which owns the maildirs. If
  10. # the script is actually run by the apache user (e.g. through PHP),
  11. # then you could use "sudo" to grant apache the rights to run
  12. # this script as the relevant user.
  13. # Assume this script has been saved as
  14. # /usr/local/bin/postfixadmin-mailbox-postdeletion.sh and has been
  15. # made executable. Now, an example /etc/sudoers line:
  16. # apache ALL=(courier) NOPASSWD: /usr/local/bin/postfixadmin-mailbox-postdeletion.sh
  17. # The line states that the apache user may run the script as the
  18. # user "courier" without providing a password.
  19. # Change this to where you keep your virtual mail users' maildirs.
  20. basedir=/var/spool/maildirs
  21. # Change this to where you would like deleted maildirs to reside.
