python实现发邮件

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
import smtplib
from email.mime.text import MIMEText
from email.header import Header
 
# 第三方 SMTP 服务
mail_host="smtp.163.com"  #设置服务器
mail_user="[e-mail]"    #用户名
mail_pass="123456"   #口令 
 
sender = '[e-mail]'
receivers = ['[e-mail]']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
 
message = MIMEText('1111...', 'plain', 'utf-8')
message['From'] = "admin"
message['To'] =  "[e-mail]"
 
subject = '222'
message['Subject'] = Header(subject, 'utf-8')
 
smtpObj = smtplib.SMTP() 
smtpObj.connect(mail_host, 25)    # 25 为 SMTP 端口号
smtpObj.login(mail_user,mail_pass)  
smtpObj.sendmail(sender, receivers, message.as_string())
print "邮件发送成功"

注意：message['From']和message['To'] 不能使用Header处理！！！
