automatic domain expiry reminder to clients

[pawan]

It would be nice.
if ISPCONFIG can send a mail to the clients certain days in advance for expiry of a service say website, webdomain or email domain.

Also respective service page there is a expiry date of service column and domain expiring in say next 15days show in the Dashboard.

This feature will really help not only the clients, but it will help the server administrator to keep track of the domain and renewals.
