        Hi,
I'm not sure what you call "macro script" or "macro plugin", but maybe
it's not that important.

The main programming language in Evolution is C. There can be made
GObject bindings (then it can be used by other languages like python
and all those, which understand GObject introspection), but it's
generated for evolution-data-serer only, not for Evolution.

You may want to engage someone knowing C, and especially glib, because
it's used heavily there. Such person could start with the example
module [1] and change it to its like-ings. He/she would be mostly
interested in the m-msg-composer-extension.c part (can delete (almost)
all the rest), and it can change it to connect to the "presend" action
of the EMsgComposer, where can be implemented the question about asking
whether the sender is correctly set (the signal handler returns whether
the message can be send). It's different from your suggested "ask on
composer open", but I think it is not a problem, and, more importantly,
it can use already implemented approach (the "presend" signal).

        Bye,
        Milan
