谁在用kloxo面板的, 发送邮件错误怎么弄?

jacksh

我把mx解析到mail.XXX.com 上面,然后webmail.XXX.com指向了IP.

现在可以在webmail.xxx.com中登录收邮件,但发不了邮件,提示:  
Hi. This is the qmail-send program at 1.
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.

<XXXXXX@qq.com>:
Sorry, no mailbox here by that name. (#5.1.1)
