python （18）在linux中如何实现定时发送邮件

 1 #!/usr/bin/env python

 3 import smtplib
 4 from email.mime.text import MIMEText
 5 import threading
 6 import time, datetime
 7 
 8 mailto_list=[""] #里面是对方的邮箱
 9 #-----------QQ邮箱发送设置----------------------
10 mail_server="smtp.qq.com"#以qq邮箱为例子，里面是QQ邮箱的服务，换成其他邮箱需要更改服务
11 mail_user=""#这是QQ邮箱的账号
12 mail_pass="这里面写上16位的编码"#直接填上密码，或者邮箱未开服务，会提醒你打开下面的链接
13 #QQ邮箱需要去官方打开服务：http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256
