Bonjour,

Matériel: VPS
Version de YunoHost: Propulsé par YunoHost 11.1.21 (stable)
J’ai accès à mon serveur : En SSH | Par la webadmin .
Êtes-vous dans un contexte particulier ou avez-vous effectué des modificiations particulières sur votre instance ? : non

Depuis hier, je ne reçois plus aucun mails de mon serveur yunohosts sur tous les comptes utilisateurs de celui ci

L’envoi ne pose aucun soucis
Juste la réception
Aucun message d’erreur

Rien non plus dans le diagnostique
https://paste.yunohost.org/raw/eyipuxiyis

J’avoue ne pas savoir où chercher et la situation est assez embêtante…

Si quelqu’un pouvait m’aider, ce serait cool

Merci d’avance

Peux-tu regarder le fichier suivant et voir s’il y a des erreurs ? /var/log/mail.log

Et est-ce que les expéditeurs externes reçoivent une erreur par retour d’email ?

crustyourmind · June 12, 2023, 10:52am

Merci pour l’aide

Non les expéditeurs ne reçoivent pas de notification de non distribution

Et oui il y a des erreurs … dans les logs des mails

J’ai rebooté le serveur et des mails tombent…
Je ne sais pas trop quoi en penser … Les ai je tous ou non ?

tituspijean · June 12, 2023, 11:36am

As-tu eu un renouvellement de certificat récemment ? (Edit: quoique rien dans les erreurs semblent indiquer un problème de certificat)

crustyourmind · June 12, 2023, 11:52am

Pas récemment (la semaine passée) mais pas eu de soucis jusqu’ici.
Le reboot semble avoir remis le serveur sur pied mais j’aimerais bien comprendre ce qu’il a pu le faire bugger

D’autant plus qu’à cette heure

J’aimerais savoir d’où ça peut venir afin de régler ce soucis

Je vais tenter d’après la littérature du forum un
sudo yunohost tools regen-conf postfix --force
après chaque régénération des certifs ssl, on verra bien
Par contre si qq un pouvait confirmer que je suis dans la bonne voie ce serait cool
