So your getting the error when sending to your company.com email domain from Yahoo? Your question isn't very clear. If that's the case, most likely its a problem on Yahoo's end in which they can't find your server or MX record, etc. If it was a problem on your own server, it would return a totally different error, not an MX record. I'd suggest contacting Yahoo.

My company mail server can send email all over the world. But only hotmail can be used to reply the email. Other than that got the error. Any idea?

What do you have as the outgoing mail address or reply to address when replying to this mail? And can you send an email directly to a valid email account on the server?
