It's been a while now since I've installed a ispc3 + rc 0.3 and have it up 'n' running. Been looking for a way to get the 'password' plugin to work with ispc3 without any luck so far.
Also, there is this 'Manage Users' plugin that lets a certain user (or some users) add/delete/edit mail accounts. Sort of a simplified Mail-Admin interface for RoundCube with an ISPConfig backend. Haven't got this to work either.
As already asked in
this thread, I am looking for any sql queries that'll do the job or any other means anyhow. So, I am looking forward for a rc 0.3 version of your plugin.
Let me know if I can help with testing or in any other way.
