This should be a valid gmail account email with @gmail.com if im not wrong
Can you test it like that?
Also keep in mind (if u will use gmail smtp) that gmail will replace the FROM and ReplyTo addresses to your gmail adress so not sure what it will come out of this.
Alternatively you could try to set smtp to your ISP smtp (most ISP provide smpt hosts something like smtp.myisp.com) with port 25 and without authentication.
