[MASOCH-L] CNAME_lookup_failed_temporarily

[Daniel Martinez]

Lista,
	Boa tarde.
Gostaria de saber a opinião de vocês.

Tenho um server de mail (QMAIL) enviando, recebendo, tudo bem ate ai.

Acontece que existe um domínio que não estou conseguindo enviar emails. 
Porque? O domínio destino tem 9 MX configurados no seu DNS.

No log do qmail  aparece: Apr 19 14:23:56 bufalo qmail:
1113931436.832552 delivery 26: deferral:
CNAME_lookup_failed_temporarily._(#4.4.3)/

Isso e correto? (ter 9 MX configurados no DNS). Tenho que patchear meu
QMAIL por causa de UM/ALGUNS domínios com mais de 9 MX teoricamente mal
configurados nos seus respectivos DNS ?

Exemplos: 

bufalo$ host -t mx gmail.com
gmail.com mail is handled by 20 gsmtp57.google.com.
gmail.com mail is handled by 10 gsmtp171.google.com.
gmail.com mail is handled by 10 gsmtp185.google.com.
gmail.com mail is handled by 10 gsmtp171-2.google.com.
gmail.com mail is handled by 10 gsmtp185-2.google.com.

bufalo$ host -t mx yahoo.com
yahoo.com mail is handled by 1 mx3.mail.yahoo.com.
yahoo.com mail is handled by 5 mx4.mail.yahoo.com.
yahoo.com mail is handled by 1 mx1.mail.yahoo.com.
yahoo.com mail is handled by 1 mx2.mail.yahoo.com.

Problema:

bufalo$ host -t mx dominio.com.br
dominio.com.br mail is handled by 10 r5d4.ns1.com.br.
dominio.com.br mail is handled by 10 yoda.ns1.com.br.
dominio.com.br mail is handled by 10 y4p17.ns1.com.br.
dominio.com.br mail is handled by 10 tarkin.ns1.com.br.
dominio.com.br mail is handled by 10 tessek.ns1.com.br.
dominio.com.br mail is handled by 10 salvage.ns1.com.br.
dominio.com.br mail is handled by 10 sithdroid.ns1.com.br.
dominio.com.br mail is handled by 10 mail.sepaco.com.br.
dominio.com.br mail is handled by 10 r2d2.ns1.com.br.

Depois foi verificar os MX do ns1.com.br e pra minha surpresa tinhan
mais MX configurados.

bufalo$ host -t mx ns1.com.br
ns1.com.br mail is handled by 10 jar-jar.ns1.com.br.
