If you haven't changed anything recently, that would seem to indicate a problem at/from yahoo, or something amiss with DNS at any rate.

I seem to recall that MX records cannot point to CNAME records (MX must point to type A record), so it seems odd that CNAME lookup is even being done. Just a thought.

Dear All,

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.

<te...@*******.com>:
CNAME lookup failed temporarily. (#4.4.3)
I'm not going to try again; this message has been in the queue too long.
-----------------error msg end----------------------------------------

we are using this qmail server hosting several domains, all others domains can receive email from yahoo,
only this "te...@*******.com" cannot receive email from yahoo,

I googled, but seems no help solution,

Any idea ?

Thanks
Sam

This is a DNS lookup failure.
Have any DNS records for the domain changed recently? Perhaps the time field wasn't updated?

We really can't help much with diagnosis w/out knowing the domain name.
