Envoie mail Python SMTP SSL

Bonjour,

je rencontre un problème avec l'envoi de mail sous python.
voila le code :
EMAIL_HOST = 'SSL0.OVH.NET'
EMAIL_PORT = '465'
EMAIL_HOST_USER = 'user@mondomaine.fr'
EMAIL_HOST_PASSWORD = 'monpasswordquivabien'
try:
print("Connection au server : " + EMAIL_HOST + ":" + EMAIL_PORT)
server = smtplib.SMTP_SSL(EMAIL_HOST, EMAIL_PORT)
server.set_debuglevel(1)
print("Authentification")
server.login(EMAIL_HOST_USER, EMAIL_HOST_PASSWORD)
print("Envoi du message")
server.sendmail(EMAIL_HOST_USER,['destinataire1@hotmail.com'], "Sujet", "Message Test")
server.quit()
print("Envoyé !")

except :
print("Error")


et voila ce que j'ai en sorti :
Connection au server : SSL0.OVH.NET:465
