Forward and keep local copies

Why is it interesting?

Modoboa already lets you define a forward and choose if you want to keep local copies in your inbox but it is a global setting which applies to all emails. Using a message filter will let you select only a subset of the emails you receive and/or run additional action.

How will it be integrated?

The existing redirect to action will be updated to add a Keep local copies option:

This change will also require to modify the sievelib module which currently does not support the :copy extension.

If you need/want/like this feature, it is time to sponsor it ;-)
