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

Greg Sims

Basic Pleskian
TITLE:
Send from domain IP addresses and use domain names in SMTP greeting
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:
CentOS Linux 7.3.1611 (Core)‬
12.5.30 Update #62
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 mailman early this morning. I reviewed the headers of the resulting emails. They were sent from the IP address associated with the Server instead of the IP address associated with the Domain.​
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​
