第二版，写成模块，可调用使用

    '''
    def __init__(self, port=25, auth=True):
        self.port = port
        self.auth = auth

    @classmethod
    def setmail(cls, host, sender, passwd, mail_to, mail_sub, content):
        '''You must set attr:

        cls.host = host

        cls.content = content

    @property
    def sendmail(self):
        '''sendmail: Start Connect server to send mail .'''
        self.message = """From: {0}

        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.settimeout(10)
        try:
            s.connect((self.host, self.port))
            # print('Connect {0}:{1} successfuly !'.format(self.host, self.port))
        except Exception:

        s.close()

        try:
            print(self.auth)
            smtpobj = smtplib.SMTP(self.host, self.port)
            if self.auth is True:

            smtpobj.sendmail(self.sender, self.mail_to, self.message.encode('GBK'))
            print('Successfully send email !')
            smtpobj.quit()
        except smtplib.SMTPAuthenticationError as error:
            print(error)
            print('认证失败,请核对用户名和密码.')
        except smtplib.SMTPException as error:
            print(error)
            print('Error: unable to send mail !')
        except Exception as e:
