The dynamic headline fader/flipper display is a highly configurable DHTML gizmo, compatible with all DHTML-capable browsers (such as Netscape 4.x or IE 4.x). Appearence, speed, display, newsfeed and more are all selectable. There's also a web frontend to make configuration even easier, available at: http://webreference.com/dhtml/dynomat/
dict_pgsql is a dictionary for the mailer postfix. It is able to get all virtual users out of a postgres database; this is very helpful if you have a large number of users who make updates on their aliases quite often. You don't have to extract all the values into system files; the entries will be fetched directly from the database.
