Quoting Arturo 'Buanzo' Busleiman <bua...@buanzo.com.ar>:

You might want to do a cvs head version install of the complete horde suite with the incubator applications and take a look at all the old and new code. http://www.horde.org. You might want to join the project and integrate the existing tool with their solid infrastructure to do what you are planning and save a few years of time. http://www.horde.org/source/using.php http://www.horde.org/source/modules.php

These are not separate modules as is normal on similar projects but utilize one another and the shared infrastructure for efficiency. You will probably be interested in and will want to install and configure all but the ones more focused on what you want to do are probably: vilma Virtual email domain administrator sork Alias for accounts, forwards, passwd, and vacation sam A Spam Assassin module passwd Password changing module from the incubator incubator Projects that are in development - "incubating" beatnik Dns frontend. http://swik.net/beatnik I'm sure I've missed some but as you install and test each module you will find them. This should save you a lot of time. The basic apps are there and need a bit of glue and polish, maybe.

I am horde user since php3.

have a great day,

ed

P.S. I didn't mention that this is a great webmail/groupware system.
