利用Python自动发送邮件

# -*- coding:utf-8 -*-
from email.mime.text import MIMEText
from email.header import Header
import smtplib

def send_mail(file_new):
f = open(file_new,'rb')
mail_body = f.read()
f.close()

msg = MIMEText(mail_body,'html','utf-8') 
msg['Subject'] = Header("自动化测试报告",'utf-8')

smtp = smtplib.SMTP()
smtp.connect("smtp.126.com")
smtp.login("username@126.com",'password')
smtp.sendmail("username@126.com","receive@126.com",msg.as_string())
smtp.quit()
print "email has send out !"

send_mail("D:\123456.txt")

注：以上代码可以实现自动发送邮件，不过在发送中文或者中英混合的文件时，会出现乱码的情况。对于主题、回复人涉及汉字的，要用Header("xxxx","utf-8")方式进行编码转换。至于内容，就不要转换成utf-8了。
