IMO amending one From: line out and adding that is a good idea,
to explicitly require a module which feature is being used.

Currently it looks like egp is loaded by mml-sec, which is loaded by
mml-smime which is loaded by mm-view which is loaded by notmuch.el as the
first module it is requiring (used try-emacs-mua to see what it is loading
and then manually parsed the output)
