Recently, anyone who sends email to my company it do not come. I have exchange 2003 server that has all the company mailbox. I check my MX record (mail from other domain comes) and it seems to be OK. We have our own DNS server.
After like 8 or 9 hrs I received mail in my yahoo account with following error from MAILER-DAEMON@yahoo.com.

Hi. This is the qmail-send program at yahoo.com.
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.
CNAME lookup failed temporarily. (#4.4.3)
I’m not going to try again; this message has been in the queue too long.

How can I resolve this issue, anyone has any idea? Is this my domain problem or it is yahoo’s problem?
Thank you in advance for allthe help
