## 基于SSL安全连接，Gmail提供的SMTP服务必须要加密传输

server = smtplib.SMTP(smtp_server, 25) # SMTP协议默认端口是25

# server.starttls() # 创建安全连接，对于'smtp.gmail.com'，端口587

server.set_debuglevel(1) # 打印信息

server.login(from_addr, passwd)

server.sendmail(from_addr, to_addr, msg.as_string())

server.quit()

if __name__ == '__main__':

smtp_server = 'smtp.163.com'

from_addr = '×××××@163.com' #从该邮箱发出邮件

passwd = '××××××' #该密码不是你用客户端登陆邮箱时所用的密码，而是设置开启smpt时设置的密码

to_addr = ['××××××@qq.com'] #该邮箱为接收邮件的邮箱

subject = 'Hello...' #邮件主题名字

#with open('names.txt','r') as fp:

# text=fp.read() #我这里是把一个名字为names.txt的文件内容读出来作为邮件内容

text = "Hello, I'm dc,send by Python..."

files = []
send_mail(smtp_server, from_addr, passwd, to_addr, subject, text, files)

把以上程序中发送邮箱、密码、接受邮箱改为自己的（记住一定要进入自己邮箱开启smtp服务），改好后把程序复制到一个.py文件中直接执行python 文件名即可。
