请教:用SENDMAIL发邮件收到奇怪退件

550 Your SMTP Server ((smtp.com.cn) [xx.xx.xx.xx]) was listed at list.dsbl.org because of the following reason: http://dsbl.org/listing?ip=xx.xx.xx.xx

这是什么原因呢?(不是open reply的问题,已经装了发信认证)

那是因为你的机子,或者你的网段做过email方面的坏事。

你得请他们把你的IP从那里去掉。

It appears that the DNS operator for xyz.com.cn has installed an

invalid MX record with an IP address instead of a domain name on the right hand side. This basically says that the sending domain XYZ has been incorrectly configured with regards to the way that it accepts mail.

What our system is doing is a verification check (for SPAM and abuse reasons) to see that the domain is in fact valid, and this check is thus failing. This means that there will actually be many destinations accross the world that will not accept mail from them, not just ourselves, though not ALL servers will refuse mail from them, eg. servers running older versions of their respective programs, some mail servers such as Microsoft exchange don't have this security feature etc.

What needs to be done to fix the problem:

The administrator of the domain xyz.com.cn needs to modify the MX entries such that there is a DNS name (either an A record or a CNAME record)

which is the DNS name of the server hosting the mail (eg. mail.xyz.co.za and NOT just it's IP address), and then they need to point the MX entry to that name (not to the IP address as is currently being done)

这里有一段国外技术支持的建议,应该已经说的满清楚了,问题出在DNS上,有谁能详细一点告诉我该怎么做吗?

能看出你的专业来

这里说你的DNS不对,可是你又没给我们看你的MX设置。

那就多学点英文,把这段看懂吧。
