        self.host = host
        self.port = port
        self.fromEmail = fromEmail
        self.fromEmailPwd = fromEmailPwd

        try:
            if self.isEnableSSL:
                smtpobj = smtplib.SMTP_SSL(self.host)
            else:
                smtpobj = smtplib.SMTP(self.host)

            # 建立连接
            smtpobj.connect(self.host, self.port)

测试结果

def sendEmailTest():
    host = 'smt.163.com'
    port = 465
    fromEmail = 'XXXX@163.com'
    portPwd = 'XXXXXXXXX' # 网易和QQ使用的是授权码
    toEmails = 'user1@163.com,user2@163.com'
    emailHelper = EmailSend(host, port, fromEmail, portPwd, toEmails, True)
    emailHelper.send('邮件测试主题', '这是一封测试邮件')
