我用的是imail8.22,能收到从雅虎发的邮件,但是发送不了到雅虎的邮件.并且没有收到任何退信.SINA也一样.
用过umail,winmail都一样,发到雅虎、新浪、还有国外的都会退信。我用的是动态域名解析.
应该怎么解决这种问题?

以下是winmail退信内容:


Hi. This is the smtp delivery program.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

=====================================================

您好！
您的邮件不能成功的递送到指定地址。这是一个永久的错误，因此不得不放弃继续递送。

首先你的动态IP本身就存在不稳定性，再加上发不通的原因：1、IP未做反解；2、IP被列入RBL；3、国际带宽影响；4、GFW拦截等等都可以造成外发有问题，建议选择尝试第三方服务器进行中继转发，应该可以解决你的问题

你的记录不详细

请贴出完整日志记录，这样便于分析问题所在。
