      @olivierlambert .
      Bonjour je sais que ce n'est pas correcte de passer par ce poste pour cette demande, mais je peux vous assurer que j'ai tout essayé depuis 1 mois pour contacter une personne chez VATES afin d'avoir des renseignements. L'envoi d'un message à toute adresse de chez vates retourne : « Le message n'a pas pu être envoyé aux destinataires suivants : [xxxxxx xxxxxxxxxx@vates.fr, sales@vates.fr] (550 - 550-Requested action not taken: mailbox unavailable
      550 invalid DNS MX or A/AAAA resource record.
      J'ai laissé plusieurs messages sur le site de VATES avec mes coordonnées mail et téléphonique. J'ai même envoyer un message avec ma messagerie perso (pas de retour d'erreur mais pas de réponse).
      Je n'ai eu qu'une seule et unique réponse de vous sur l'adresse d'inscription à ce site le 27 mars me demandant plus de précision, mais avec le fameux message d'erreur lors de la tentative de réponse.
      Je suis le dirigeant de Ressources Conseils Informatique, et j'aimerai vraiment savoir si vous pouvez m'aider pour des transferts de compétences sur XCP-NG.
      Merci de me donner au moins une réponse même négative.
      Cordialement
      Robert COLIN

        @Robert-COLIN it would be just fair to give at least an english summary of your post

          @borzel .
          Is just I can't have contact with Olivier. Mail doesn't work. And I would like service from Vates company. I'm sorry to use this way but I tried by all that I can for one month. Sorry for disturbing this post.

            I've forked the topic, since there was no reason to have this discussion on the original topic.

                @Robert-COLIN If you using a self build mail setup, check it first:
                550 - 550-Requested action not taken: mailbox unavailable
                550 invalid DNS MX or A/AAAA resource record

                Sounds like your mail server is not correctly resolving the vates DNS/MX entry. Did you check that on the mailserver?

                  To vates.fr:

                  Seems your DNS MX records are CNAMEs (aliases). They should not.

                  $ host -t mx vates.fr
                  vates.fr mail is handled by 50 smtp2.vates.fr.
                  vates.fr mail is handled by 10 smtp1.vates.fr.
                  
                  $ host smtp1.vates.fr.
                  smtp1.vates.fr is an alias for mail1.vates.fr.
                  mail1.vates.fr has address 212.129.1.64
                  
                  $ host smtp2.vates.fr.
                  smtp2.vates.fr is an alias for mail2.vates.fr.
                  mail2.vates.fr has address 212.129.1.118
                  
                  $ host -a smtp1.vates.fr.
                  [...]
                  smtp1.vates.fr.         600     IN      CNAME   mail1.vates.fr.
                  
                  $ host -a smtp2.vates.fr.
                  [...]
                  smtp2.vates.fr.         600     IN      CNAME   mail2.vates.fr.
                  

                  This can be the reason that some mail servers don't deliver mail to you.

                  See RFC 2181:

                  "The domain name used as the value of a NS resource record, or part of
                  the value of a MX resource record must not be an alias. Not only is
                  the specification clear on this point, but using an alias in either
                  of these positions neither works as well as might be hoped, nor well
                  fulfills the ambition that may have led to this approach. This
                  domain name must have as its value one or more address records.
                  Currently those will be A records, however in the future other record
                  types giving addressing information may be acceptable. It can also
                  have other RRs, but never a CNAME RR.

                  Searching for either NS or MX records causes "additional section
                  processing" in which address records associated with the value of the
                  record sought are appended to the answer. This helps avoid needless
                  extra queries that are easily anticipated when the first was made.

                  Additional section processing does not include CNAME records, let
                  alone the address records that may be associated with the canonical
                  name derived from the alias. Thus, if an alias is used as the value
                  of an NS or MX record, no address will be returned with the NS or MX
                  value. This can cause extra queries, and extra network burden, on
                  every query. It is trivial for the DNS administrator to avoid this
                  by resolving the alias and placing the canonical name directly in the
                  affected record just once when it is updated or installed. In some
                  particular hard cases the lack of the additional section address
                  records in the results of a NS lookup can cause the request to fail."

                    Thank you for your help, we have removed smtp2 which did not exist and changed smtp1 to be an A record instead of CNAME 🙂
