CNAME lookup failed temporarily. (#4.4.3)

[bokken]

Hi,

I have an issue with Qmail, when i send an email to "*@grupobbva.com" and qmail response was "CNAME lookup failed temporarily. (#4.4.3)".

$ nslookup grupobbva.com
Server: XXX.XXX.XXX.XXX
Address: XXX.XXX.XXX.XXX#53

Non-authoritative answer:
*** Can't find grupobbva.com: No answer

$ nslookup -type=mx grupobbva.com
Server: XXX.XXX.XXX.XXX
Address: XXX.XXX.XXX.XXX#53

Non-authoritative answer:
grupobbva.com mail exchanger = 100 mail5.grupobbva.com.
grupobbva.com mail exchanger = 100 mail6.grupobbva.com.
grupobbva.com mail exchanger = 100 mail7.grupobbva.com.
grupobbva.com mail exchanger = 100 mail8.grupobbva.com.
grupobbva.com mail exchanger = 100 mail9.grupobbva.com.
grupobbva.com mail exchanger = 100 mail1.grupobbva.com.
grupobbva.com mail exchanger = 100 mail2.grupobbva.com.
grupobbva.com mail exchanger = 100 mail4.grupobbva.com.

Authoritative answers can be found from:
mail5.grupobbva.com internet address = 89.107.180.136
mail9.grupobbva.com internet address = 89.107.180.31
mail1.grupobbva.com internet address = 89.107.180.16
mail2.grupobbva.com internet address = 89.107.180.17
mail4.grupobbva.com internet address = 89.107.180.135

The response of DNS Server when Qmail asks, is the same, i sniffed the trafic.

For resolve this issue I have created this domain on my DNS Server with those values and one DNS type A.

This issue is problem of Qmail? my DNS Server? misconfigured DNS Server of grupobbva.com?

Hi,

Make sure that /etc/resolv.conf is readable to 'others':
# ls -l /etc/resolv.conf
-rw-r--r-- 1 root root 0 2009-09-19 05:56 /etc/resolv.

Also check that nameservers set in /etc/resolv.conf on Parallels Plesk server can get MXes of grupobbva.com and can resolve A records for those MXes.

And lastly it can be caused by the fact that grupobbva.com has too many MX records defined and response from DNS server exceeds limit of 512 bytes. If this is the case then you can use one of qmail patches:
http://lifewithqmail.org/lwq.html#dns-patches

You can refer to http://kb.odin.com/en/1161 for details on applying qmail patches to qmail shipped with Parallels Plesk.

Hope this helps.
