I have installed ISPConfig on Ubuntu 8.04 thanks to How-To. Also i have installed Squirrelmail for webmail access. How can user that has access to webmail modify mail blacklist (whitelist) and out-of-office message from Squirrelmail (installed as tool for ISPConfig)?
can this: http://www.squirrelmail.org/plugin_view.php?id=146 be used or modified and then used for this
I don't think it will work (it's also pretty old, was probably written for SpamAssassin 2, not 3), but you can try it.
