python自动发送QQ邮箱

import smtplib
from email.mime.text import MIMEText

msg_from = '[email protected]'  # 发送方邮箱
passwd = 'zbynuxgobwlxebid'  # 填入发送方邮箱的授权码
msg_to = '[email protected]'  # 收件人邮箱

subject = "python邮件测试"  # 主题
content = "邮箱内容~" # 正文
msg = MIMEText(content)
msg['Subject'] = subject
msg['From'] = msg_from
msg['To'] = msg_to
try:
    s = smtplib.SMTP_SSL("smtp.qq.com", 465)# 邮件服务器及端口号

    s.login(msg_from, passwd)
    s.sendmail(msg_from, msg_to, msg.as_string())
    print "发送成功"
except s.SMTPException, e:
    print "发送失败"
finally:
   s.quit()

还需在QQ邮箱设置smtp授权码 如：
