[RESOLU] Messages provenant de Yahoo considérés comme spam

,

Bonjour,

Certains messages envoyés par Yahoo sont considérés par mon serveur de mail Yunohost comme SPAM.

Voici ce que me dit Rainloop sur ces mails (ce qui semble être la raison du classement en SPAM):

dkim=neutral reason=“invalid (public key: DNS querry time out for s2048._domainkey.yahoo.com)” header.d=yahoo.com

J’ai recherché tout ce qui concerne DKIM sur ce forum, et ça concerne la mise en place d’un serveur DKIM, ce qui ne semble pas être mon problème.

Voici les en-têtes récupérés par roundcude pour être plus complet:

Je remarque que dans “return path” il est fait mention du nom d’utilisateur de mon correspondant XXX mais que le nom de domaine après le @ n’est pas yahoo.com mais le mien: mondomaine.net
Est-ce normal ?

Avez-vous une idée du problème ?
Dois-je regarder quelque part dans les logs ?

Bonjour,

Rétrospectivement il semble que cet incident qui m’a classé certains mails en SPAM doit provenir de coupures internet.
Hier la box internet derrière laquelle se trouve mon serveur Yunohost a eu de multiples déconnexions d’internet.
Pensez-vous que c’est ce qui a pu faire échouer cette vérification de l’expéditeur:

dkim=neutral reason=“invalid (public key: DNS querry time out for s2048._domainkey.yahoo.com)” header.d=yahoo.com

Si oui je met ce post en résolu.
