I put following together, it is usable as part (the beginning) of
hook/compose_created script for Lua plugin:

------------------------------------------------------------------------------

local compose_window = ...
local do_check = false
[[ evaluate conditions ]]
if (do_check) then
 choice = clawsmail.alertpanel("Reply check","is this intended?","Yes","No")))
 compose_window:popup()
 [[ modify compose window parameters ]]
end

------------------------------------------------------------------------------

There are just placeholders for evaluating whether you should do
something, i.e. you are really replying to yourself, and modifying
parameters of compose window to change it to be sent to someone else.
This needs to be customized for you and your environment.

This approach currently requires building Claws Mail (or at least Lua
plugin) from source, as Lua plugin is not yet present in official source
repository.
