Hi,
About half a year ago I finished (with help from Ruby guru Remco van 't
Veer) a simple e-mail management extension. With it you can manage a
small postfix virtual domain. A Postfix virtual domain allows you to
forward e-mail to another e-mail adres. The extensions allows you to
enter the redirects. It also supports crude but effective aliases and
mail-lists. In addition the Postfix configuration is verified and
instructions will be displayed if something is not right.
Please find attached a comp, it should make it quite clear what the
extension does. If the attachment did not come through, you can also
find it here: http://www.grons.nl/radiantpostfixextension.png
If anyone is interested in using this, please let me know and I will put
the code and documentation somewhere. Where? Suggestions are welcome.
MIT licensed of course. Note that I am not interested in extending the
extension 
Regards,
Erik.
