# Really crude attempt at taking all users from a local 
# passwd file (/etc/shadow) and creating postfixadmin mailboxes for them.
#
# The script outputs some SQL, which you need to then insert into your database
# as appropriate.
#
# Notes:
#  1) Change $mydomain and $true as required.
#  2) Ideally it should parse /etc/passwd, or call the getpw()? function and
#     populate someone's name if known.
#  3) There's plenty of room for improvement.
