如何设置。比如发信失败用。用中继 SMTP 服务器继续发送？

我才是大雄

WINWEBMAIL 里 会设置。就是 发信失败。比如到 雅虎 SINA 被退信后。就由 我设置的 QQ 中继 SMTP 服务器发信。。
但是 MD 里设置的好像没效果  
下面是一段退信记录。后面有 SMTP.QQ.COM 难道用 QQ 中继发信失败了？还是我设置不对？请高手指点

现在有点常识的大邮局都做了验证FROM的限制来禁止别人通过它的帐号中继，如今想要找到免费又有效的中继越来越难了。

我才是大雄

唉。。。。。难道就没办法了么。。QQ 的 VIP 邮箱。SMTP 蛮好用的。。。。

wxhsh

就是因为好用才洁身自好，如果能随便就被人家当中继用，早就进黑名单了。

所以 一些大得黑名单一定要用
不能因为怕误拦截而不采用黑名单
从而助长某些不自律的邮局

redif

有专门提供  这些中继 服务  的  公司

EN,需要的话，我们免费提供一个中继帐号试用。
