能发送邮件，但是不能收邮件

zinph

在公司服务器上面建立了一个邮件系统，很奇怪的是可以跟大部分的邮件服务商发送。但是不能收邮件，在用sina的免费邮箱中发送，被退回，提示如下This is the mail system at host mail3-117.sinamail.sina.com.cn.I'm sorry to have to inform you that your message could notbe delivered to one or more recipients. It's attached below.For further assistance, please send mail to postmaster.If you do so, please include this problem report. You candelete your own text from the attached returned message.                   The mail system<zinph@kisonmedical.cn>: host mail.kisonmedical.cn[218.106.248.120] said: 553    This target address is not our MX service client. (in reply to RCPT TO    command)但是我们公司的服务器地址并不是这个呀，有没有高人指点一下，把这个218.106.248.120换成公司服务器正确的IP？

域名的 mx记录是否指向？
