Merci pour ta réponse.
Pour alimenter la boule de cristale, il s'agit bien d'un vieux server sme7.0 en mode serveur uniquement. Pas de contribs particulières installées à ma connaissance.
Dernière manipulation est l'augmentation du quota d'une boîte mail.
Les utilisateurs peuvent envoyer des messages à des destinataires externes, les messages arrivent bien. En revanche, les utilisateurs ne reçoivent plus de message. Et les expéditeurs n'ont pas de message indiquant l'impossibilité de délivrer le message.
J'ai l'impression que les messages arrivent mais ne sont pas redistribués dans les boîtes utilisateur.
J'ai fait un qmail-stat :
# bin/qmail-qstat
messages in queue: 199
messages in queue but not yet preprocessed: 12
