python发送QQ邮件

#encoding=utf-8

__author__ = 'ds'

#文件名称冲突
from email.mime.text import MIMEText
import smtplib

if __name__ == '__main__':
msg = MIMEText(_text='SMTP test', _charset='utf-8')
#输入Email地址和口令:
from_addr = 'XXX@qq.com'
password = 'XXX'
# 输入SMTP服务器地址:
smtp_server = 'smtp.qq.com'
# 输入收件人地址:
to_addr = 'XXX@sina.cn'

#SMTP协议默认端口是25
server = smtplib.SMTP(smtp_server, 25)
server.set_debuglevel(1)
#server.starttls()
#server.connect(host=smtp_server, port=25)
#server.esmtp_features["auth"]="AUTH_LOGIN"
server.login(from_addr, password)
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()

测试之后一直报454的错误，原来是QQ邮箱将邮件的SMTP服务关闭了，外部无法访问

打开QQ邮箱账户->账户安全，将SMTP服务和POP3服务打开即可
