Well, not quite the end. But close. Google will let you use the remote SMTP servers to send the message, removing the need to fill “sender” and “from” in the message header with different addresses. But if those remote SMTP servers are hopelessly lame and you are using GMail to avoid using them in the first place … you’re still SOL.
Official Gmail Blog: Send mail from another address without “on behalf of”
We heard your request for another option that wouldn’t show the “on behalf of” text loud and clear, and now there’s a new option that does just that. Instead of using Gmail’s servers to send the message, we’ll use the servers where your other email address lives. Since Gmail isn’t the originating domain, we don’t have to include “Sender” info in the header. No more “on behalf of.”
