eM Client’s Forward as Original is usually applied to a received message in your Inbox that you want to send to someone else and have it appear as coming from you. It does the same as Forward, just without the Forward Header in the email body. It is not the same as resend, so saying we have Forward as Original , is not a valid response to the user’s requests for a resend option.
I would also welcome a resend option in eM Client.
