I'm looking for a way that users can set their own vacation/out of office replies. I've looked around in the control panel and in SquirrelMail, but I haven't found anyhting yet. I've used Horde/Imp on some other hosts and know it has the ability to set vacation messages, however I don't really want to install Horde if I can help it.
Does anyone have any suggestions? I'd prefer something that the user could do themselves (i.e. via a webpage)?
