sendmail on GPIO get +5v

skulle måske have skrevet lidt mere om det..

har en pi 2 når jeg trykker på en knap (giver en GPIO pin +5v) så sender den en mail

#import mod
import smtplib
from email.mime.text import MIMEText
import RPi.GPIO as GPIO
import time
#setup gpio pins
GPIO.cleanup()
GPIO.setmode(GPIO.BCM)
GPIO.setup(23, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
#Print message on screen
print "Push button to send email,"
#start loop
loop = "1"
while loop == "1":
        #test GPIO for input
        if GPIO.input(23):
                #create email
                message = """Test email send via RPi and Python"""
                msg = MIMEText(message)
                msg['subject'] = 'Rpi test'
                msg['from'] = '<afsenders@mail.adresse>'
                msg['to'] = 'modtager@mail.adresse'
                # send mail
                s = smtplib.SMTP('smtp.server:port')
                s.login('smtp_bruger' , 'smpt_kode')
                s.sendmail(msg['From'], msg['To'], msg.as_string())
                s.quit
                print "Email sent"
                time.sleep(2)
        while GPIO.input(23):
                pass
