* EGroupWare - EMailAdmin IMAP via Plesk                                    *

* Written and (c) 2006 by RalfBecker-AT-outdoor-training.de                 *
* ------------------------------------------------------------------------- *
* emailadmin plugin for plesk:                                              *
* - tested with Plesk7.5 under Linux, but should work with other plesk      *
*   versions and Windows too as it uses plesks cli (command line interface) *
* - this plugin ONLY works if you have root access to the webserver !!!     *
* - you need to have mail activated for the domain in plesk first           *
* - you need to configure the path to plesk's mail.sh or mail.exe cli by    *
*   editing this file (search for psa_mail_script) for now                  *
* - to allow the webserver to use the mail cli under Linux you need to      *
*   install the sudo package and add the following line to your sudoers     *
*   file using the visudo command as root:                                  *
*   wwwrun ALL = NOPASSWD: /usr/local/psa/bin/mail.sh                       *
*   Replace wwwrun with the user the webserver is running as and, if        *
*   necessary adapt the path to mail.sh.                                    *
*   PLEASE NOTE: This allows all webserver users to run the mail.sh script  *
*                and to change the mail configuration of ALL domains !!!    *
* => as with the "LDAP, Postfix & Cyrus" plugin the plesk one creates mail  *
*    users and manages passwords, aliases, forwards and quota from within   *
*    eGroupWare - no need to additionally visit the plesk interface anymore *
