A la base je voulais changer le hostname car quand j'écrivais d'un mail vers lui-même j'avais cette erreur du MX d'ovh : status=deferred (delivery temporarily suspended: lost connection with mx0.ovh.net[213.186.33.32] while receiving the initial server greeting

Depuis que j'ai changé le hostname j'ai cette erreur sur tous les emails.

Je piétine, dois-je creuser du côté de mydestination et virtual_mailbox_domains ?

Merci à quiconque pourrait aider.

Deux mois plus tard, j'ai enfin pris le temps de tester tout cela ^^

J'ai créé sur le vps un domaine du type mondomaine.org et j'ai créé un reverse dans le bind du domaine avec reverse.mondomaine.org qui pointe vers l'ip du serveur.

Alors j'ai dû modifier quelques fichiers supplémentaires dans lesquels j'ai trouvé référence du nom du serveur :
/etc/hostname
/etc/mailname
/etc/postfix/main.cf
/etc/hosts
/etc/sysconfig/network

Mais je pense qu'il en manque encore, d'ailleurs dans mes logs certains mails tentent encore de partir de postmaster@vps...ovh.net

D'ailleurs plus aucun mail ne part et j'ai des choses très space dans les logs.

Any idea ?

[Isendel]

Merci bien je vais tester tout cela.

Editer le fichier network :

nano /etc/sysconfig/network

ajouter :

HOSTNAME=nomduserveur.nomdudomaine.tld

enregistrer (CTRL+O) > fermer (CTRL+W)

Editer le fichier hosts :

nano /etc/hosts

ajouter :

ip.du.serveur.123 [Tabulation] nomduserveur.nomdudomaine.tld [Tabulation] hostname 
Ce qui est en italique est optionnel

enregistrer (CTRL+O) > fermer (CTRL+W)

Vérifier que les modifications ont bien été prises en compte en saisissant la commande :

hostname

si vous obtenez la réponse :

nomduserveur.nomdudomaine.tld

C'est gagné, il ne vous reste plus qu'à redémarrer le service :

/etc/init.d/network restart

Bonjour à tous,

J'ai pas mal creusé la question des emails ces derniers temps et j'arrive enfin à obtenir 10/10 chez mail tester.
Malgré tout, il reste un paramètre qu'il serait bon de modifier, à mon avis, c'est le nom de la machine.

Je précise que j'ai une R3 donc centos.

Pour trouver et éditer le nom de la machine j'ai trouvé /etc/hostname
J'ai en amont créé un reverse sur un domaine que je pensais utiliser en tant qu'hostname.

Ma question est simple, une fois que j'aurai modifié le nom d'hôte, il en est fait référence dans beaucoup de fichiers de conf (entre autre). Auriez-vous une liste exhaustive ou à peu près des fichiers à éditer pour que tout soit en ordre ?

Si le nom de la machine demeure celui par défaut, quels sont les risques ?
