import smtplib        from email.mime.text import MIMEText        from email.utils import formataddr                  msg = MIMEText('xaaxaxaxafdjikgjhdjfg', 'plain', 'utf-8')        msg['From'] = formataddr(["张三",'zhangsan@126.com'])        msg['To'] = formataddr(["李四",'lisi@163.com'])        msg['Subject'] = "邮件主题"                  server = smtplib.SMTP("smtp.126.com", 25) #端口        server.login("zhangsan@126.com", "asdfadfsdfa")        server.sendmail('zhangsan@126.com', ['lisi@163.com',‘wangwu@163.com’], msg.as_string())        server.quit()
