Bonjour,
Ci-dessous un problème que je n'arrive pas solutionner malgré mes recherches sur le WEB:

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:
CentOS Linux 6.10 (Core)‬
12.5.30 Update #55
PROBLEM DESCRIPTION:
We set the following option in Mail Settings at the server level:

"Send from domain IP addresses and use domain names in SMTP greeting"

We can see /etc/postfix/master.cf is updated with additional configuration data including smtp_bind_address and smtp_helo_name. This information matches our domains and associated IP addresses.

We distributed email using Postfix early this morning. I reviewed the headers of the resulting emails. They were sent from the IP address associated with the Server sxxxxxxx.onlinehome-server.info instead of the IP address associated with the Domain.(ex:aleria.fr)
STEPS TO REPRODUCE:
ACTUAL RESULT:
Email sent from Server IP Address
EXPECTED RESULT:
Email sent from Domain IP Address
Pouvez-vous m'aider à résoudre ce gros problème.
J'ai lu une grande partie de vos sujets pour ce genre de problème mais je n'ai pas trouvé de solutions pour régler ce problème qui paralyse tous les sites que je gère sur ce serveur.
Un Immense Merci
Yan D. Alaury
