Вы должны объявить переменную-сервер в качестве глобальной

global server 
server = smtplib.SMTP(vari1.get(), 587) 

Кроме того, вы должны исправить функцию , вы должны объединить данные. Если вы a, b вы создаете кортеж: (a, b) и не требуемую строку

def th(): 
    contents = text.get("1.0", END) 
    subject = assa.get() 
    message = "Subject: {}\n\n{}".format(subject, contents) 
    server.sendmail(vari2.get(), toaddrs12.get(), message) 
    server.quit()

     self._geom = '200x200+0+0' 
     master.geometry("{0}x{1}+0+0".format(
      master.winfo_screenwidth() - pad, master.winfo_screenheight() - pad)) 
     master.bind('<Escape>', self.toggle_geom) 

    def toggle_geom(self, event): 
     geom = self.master.winfo_geometry() 
     print(geom, self._geom) 
     self.master.geometry(self._geom) 
     self._geom = geom 


app = FullScreenApp(root) 


def fn(): 
    def th(): 
     contents = text.get("1.0", END) 
     subject = assa.get() 
     message = "Subject: {}\n\n{}".format(subject, contents) 
     server.sendmail(vari2.get(), toaddrs12.get(), message)
