Hi John, Thanks for you answer, which led me to the correct configuration. It was all about the "subject" missing from my way of implementing the Service ; as the function gmail.New() is deprecated, gmail.NewService() is to be used instead...but it does not implement - yet - the "subject" prop.
A discussion is still opened to fix this lack of code: https://github.com/googleapis/google-api-go-client/issues/379 This describes exactly the code you sent me (btw, I don't know I received your answers by mail but they are not displayed here on groups.google.com)...which is working like a charm.
