# Example script for removing a Maildir domain top-level folder
# from a Courier-IMAP virtual mail hierarchy.

# The script only looks at argument 1, assuming that it 
# indicates the relative name of a domain, such as
# "somedomain.com". If $basedir/somedomain.com exists, it will
# be removed.

# The script will not actually delete the directory. I moves it
# to a special directory which may once in a while be cleaned up
# by the system administrator.

# This script should be run as the user which owns the maildirs. If 
# the script is actually run by the apache user (e.g. through PHP),
# then you could use "sudo" to grant apache the rights to run
# this script as the relevant user.
# Assume this script has been saved as
# /usr/local/bin/postfixadmin-domain-postdeletion.sh and has been
# made executable. Now, an example /etc/sudoers line:
# apache ALL=(courier) NOPASSWD: /usr/local/bin/postfixadmin-domain-postdeletion.sh
# The line states that the apache user may run the script as the
# user "courier" without providing a password.


# Change this to where you keep your virtual mail users' maildirs.
basedir=/var/spool/maildirs

# Change this to where you would like deleted maildirs to reside.
trashbase=/var/spool/deleted-maildirs
