This may not be the proper forum, but

I'm hoping someone can atleast point me in the right direction.

I've got squirrel, horde and neomail set up for clients.

I've had a client ask if there is a way for each email user to set and/or change their own email password without having to go into cpanel.

Is there a hack or a third party program available.

Any and all suggestions are welcome

Thanks !
