[CentOS-fr] Send from domain IP addresses and use domain names in SMTP greeting​

[Yan-David Alaury]

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
<http://s16251634.onlinehome-server.info/>* instead of the IP address
associated with the *Domain*.(ex:aleria.fr)
STEPS TO REPRODUCE:

   - Mail setting to: "Send from domain IP addresses and use domain names
   in SMTP greeting"
   - create a domain with an ip address that is different than the server
   ip address
   - review configuration in /etc/postfix/master.cf
   - create a mailman distribution list for the new domain with one test
   email address
   - send an email to the mailman address for distribution
   - review the headers of the resulting email -- specifically the sending
   IP Address

*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
