The new version is amazing, but this is really missing... My clients want something like a squirrelmail plugin for password change, auto reply and forward, or a panel just for them. like http://mysite.com.br:8080/user them a client log on with his email and password. there he can create a forward or auto reply and change his password. if you have a third-part script that do that, please post here. Thanks.
I have done something like this for Roundcube webmail. You can have a look here: http://www.howtoforge.com/forums/showthread.php?t=33470
