python smtplib发送邮件

最近看到了一个防止DDOS的python脚本，不过其邮件通知功能一直不成功，而最近又在学习python 。打开源码查看，发现有调用smtplib 进行邮件发送 。不过因为里面有调用配置文件参数，略有点复杂。先从网上查了查smtplib的用法 。通过smtplib进行gmail发送代码示例：

#!/usr/bin/env python
import smtplib
import sys
import email.mime.text
# my test mail
mail_username='361way@gmail.com'
mail_password='test'
from_addr = mail_username
to_addrs=('test@361way.com')
# HOST & PORT
HOST = 'smtp.gmail.com'
PORT = 25
# Create SMTP Object
smtp = smtplib.SMTP()
print 'connecting ...'
# show the debug log
smtp.set_debuglevel(1)
# connet
try:
    print smtp.connect(HOST,PORT)
except:
    print 'CONNECT ERROR ****'
# gmail uses ssl
smtp.starttls()
# login with username & password
try:
    print 'loginning ...'
    smtp.login(mail_username,mail_password)
except:
    print 'LOGIN ERROR ****'
# fill content with MIMEText's object
msg = email.mime.text.MIMEText('Hi ,this is a test mail')
msg['From'] = from_addr
msg['To'] = ';'.join(to_addrs)
msg['Subject']='hello , today is a special day'
print msg.as_string()
smtp.sendmail(from_addr,to_addrs,msg.as_string())
smtp.quit()

代码挺简单，使用时，只需要把用户、密码、收件人、主题及内容更换即可。
