3 # mailshears, to prune unused mail directories.
5 # Mail accounts for virtual hosts are stored in SQL, and managed by
6 # Postfixadmin. However, the physical directories are handled by
7 # Postfix/Dovecot and are left untouched by Postfixadmin. This is good
8 # for security, but comes at a cost: Postfixadmin can't remove a
9 # user's mail directory when his or her account is deleted.
11 # This program compares the list of filesystem accounts with the ones
12 # in the database. It outputs any accounts that exist in the
13 # filesystem, but not the database.
16 # Define a usage string using the program name.
