It is not excluded in the patch, it is added to "cc" only if "wide" is
specified.

Please have a look at the mail examples I sent in other posts.

It have a valid "Reply-To" and with the patch I sent it is used instead
of "from".

Don't know, but it is better than receiving warning mails from gmail
like this:

From: Mail Delivery Subsystem <mailer-daemon@googlemail.com>
Subject: Delivery Status Notification (Failure)

Which is not an improvement IMO.

Note that with the current state it is impossible to reply with Gnus on
github with `R' `F' or whatever without beeing rejected; 
The patch I sent fix this.

The point is that with the patch I sent + the headers of the rejected
mail and the original mail where I reply to, you will be able to
understand what happen and fix it.

Thanks.
