+# 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.
