ESMTP (Login)

我用MaxBulk Mailer邮件群发
但是每次都不成功 我得信箱是dongying@sina.com 密码asdf123
在设置里 我添的是
SMTP主机 smtp.sina.com
身份验证 ESMTP (无/pop/esmtp/apop) md5 chllenge-response (login/plain/md5 chllenge-response)
帐户识别号码 dongying
口令 asdf123
请问哪里错了
为什么发送失败

ESMTP，英文全称是“Extended SMTP”，顾名思义，扩展SMTP就是对标准SMTP协议进行的扩展。它与SMTP服务的区别仅仅是，使用SMTP发信不需要验证用户帐户，而用ESMTP发信时，服务器会要求用户提供用户名和密码以便验证身份。验证之后的邮件发送过程与SMTP方式没有两样。
