I'm OK with you, but this works is one part of a biggest project in parse, restructure email. And in this project, i need to have a soft structure to send mail.
And for me it's very interresting to see exactly how a module could be writting. In this case, this part of developpement is my own reflexion about "mysterious of a module".
But you're note is interresting, and i think , that i will try to "patch" an existant module.
Thank You.
