检查一下你的ＭＸ记录是否正确。或是给出设定来看看。

你的问题和我一样,不过我现在已经解决,请检查你的A记录和MX记录指向是否正确

我現在也遇到這樣的問題。要怎樣做呢？

还有一种可能就是反垃圾级别太高了

但是我用的是趨勢的scanmail,除上面那個郵件服務器發過來不能收到,其它的都可以收到.我不知問題出在哪兒?

第一個問題可能性:<br>你改過你自已的MX記錄,但對方沒有做相應調整.<br>對方DNS解釋你的MX時出錯或超時(與你無關)<br>
第二個問題可能性:<br>與第一個差不多<br>對方的服務器與你的服務器握不成手, 准備晚點再握手,郵件是提醒你第一次握手失敗,你不用補發出件,服務器會再試一次.
