We need a simple PHP code filled in within an already existing generic framework provided by Atmail ([login to view URL]) for allowing users to create/change auto-reply and mail-forwarding options against a custom mail-server backend (preferably Postfix).
The framework (plugin) is available here: [login to view URL]
Atmail demo is available on Atmail website [login to view URL]
Documentation on writing a plugin for Atmail is also available here http://support.atmail.com/display/DOCS/Creating+Plugins.
However please note that we DON'T need the entire plugin. You are only required to provide some lines of working code to include in the file [login to view URL] (which you can find it in the archive [login to view URL] ) so that webmail users can define/update/save their autoreply and forward preferences.
