Good I figured that might be the issue. Will contact them directly and let them 
know hey have a misconfiguration at hand.

Thanks a lot guys. Your help was much appreciated!

Same for the MX but can't test ANY yet. But since your reply is empty it seems 
that could explain it?

Sadly not right now but I can probably get access to one this week. And since 
it's not a common address I send to and my contact there is not available right 
now I am not sure we can easily test this. I just hope this will stay a single 
issue and not suddenly crop up with more domains.

Will try to find something else to test. It could be specific to my qmail 
instance for some reason but I'll have to debug further.

Thanks for the heads up so far!

Another question, do you have another QMT that you could send it from, 
so it can determine that it's not just something with that particular 
QMT you're running? If you need I could test for you.

[qmailtoaster] CNAME lookup failed temporarily (#4.4.3)

[Sebastian Grewe]

Hey List!

I am currently getting this error message when trying to send a mail to a 
domain (audi-kiel.de). I Googled and figured out that it’s caused by Qmail not 
handling the ANY DNS request properly when exceeding 512 bytes in answers. 
Strangely this was linked to a DNS patch in Qmail but when I checked my Source 
RPM this patch was applied properly. I even tried re-compiling it and 
re-installing the package to no avail.

Does anyone else have a hint why this seems to be an issue? I haven’t had 
problems so far and this only started recently for that domain.

Things I checked:

* DNS Server Settings, I ran against Google DNS and my Host Provider DNS, both 
causing this
* Qmail Patches, they are all applied and I can see the changes in source code 
being correct for large DNS responses
* Restart Qmail, put in for good measure but of course I did that too 
(including killing processes)

Full error message:

CNAME lookup failed temporarily. (#4.4.3)
I'm not going to try again; this message has been in the queue too long.

I am starting to think this is actually caused by a DNS issue on their end and 
not my end:

$ dig mx audi-kiel.de

If you all agree on this I will get in touch with them to get this fixed. Maybe 
they moved their mail hosting recently which would explain those weird MX 
records :-)

Sebastian

Re: [qmailtoaster] CNAME lookup failed temporarily. (#4.4.3)

Hi Dan,
  Correct in all but in this case it actually was their DNS screwed up.
I use dnsmasq as my resolver. It easy to configure and quick. It also
seems to handle oversized responses as well.
  Thanks.

I've been through this a number of times with people -- your mail server has no need of being a DNS server as well, but 
it will rely HEAVILY on whatever DNS server you provide it (usually in /etc/resolv.conf).


One popular option is pdns-resolver (available from EPEL).
 - NOTE: Do not confuse pdns-recursor with pdns -- the recursor is a DNS CLIENT (lookup service), not a server... but 
it's fast and efficient.


One major cause of the CNAME issue is not really based on CNAMEs at all -- rather it is a buffer overflow in the response 
from the DNS authoritative server. (DNS replies are supposed to be -- oops, used to be -- limited to 5xx characters. 
Newer updates to the spec have made that a larger buffer, but many DNS clients can't handle the overflow, and so error 
out... and the assumption is made that it is a CNAME caused error... an assumption that is not always correct.

[qmailtoaster] CNAME lookup failed temporarily. (#4.4.3)

[Tony White]

Hi folks,
  This probably been covered somewhere before it is so
frustrating I want to see if any one can explain this issue.

:
CNAME lookup failed temporarily. (#4.4.3)
I'm not going to try again; this message has been in the queue too long.

The question is this...
dig mx for this domain returns a trendmicro mail server.
Yet I get this error.
The receiver actually has a mail server ie mail.adomian.com.au which
will accept mail. I can manually send email to the trendmicro as well.
Yet Qmail gives this error every time!

Anyone any idea?

TIA

--
best wishes
  Tony White

Hi All,

I'm getting CNAME lookup failed temporarily. (#4.4.3) fairly frequently

QmailToaster is patched with Big-DNS patch?  According to the wiki it is
(its at the bottom of this list)

http://wiki.qmailtoaster.com/index.php/Patches_included_with_QmailToaster

If it is patched ... any idea why I am getting this failure?

Patch is here:

CNAME lookup failed temporarily. (#4.4.3)
I'm not going to try again; this message has been in the queue too long.

Ideas?

Thanks,

Dave

[qmailtoaster] CNAME lookup failed temporarily. (#4.4.3)

[Sam - SD]

Dear All,

we have a qmail server for several years and running without any problem.

Few days ago, one customer forward me a error msg, which is
--error msg start---
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.

:

-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
