Forwarded to devs Postfix outgoing IP address does not change

TITLE:

Postfix outgoing IP address does not change​

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

PLESK Onyx, CentOS Linux release 7.5.1804, kernel 3.10.0-862.14.4.el7.x86_64, x86_64.
postfix-2.10.1-6.0.1.el7.centos.x86_64​

PROBLEM DESCRIPTION:

When the outgoing IP is changed in https:/..../plesk/server/mail/
the change is correctly done in main.cf as
smtp_bind_address = 95.216.90.225

However, even after stop/start of postfix, the outgoing mail is still sent from our eth0 address, 95.216.38.116.

Tested by sending mails to myself and examining the Received headers.​

STEPS TO REPRODUCE:

1. change the postfix outgoing mail IP address after the original was blocked by SORBS.
2. Stop/start postfix.
3. Send test mail out.
4. Examine headers.

ACTUAL RESULT:

Mail still gets sent out from the old address​

EXPECTED RESULT:

Mail should be sent from the selected address.​

ANY ADDITIONAL INFORMATION:

​

YOUR EXPECTATIONS FROM PLESK SERVICE TEAM:

Confirm bug​

Please check that your postfix has 2.7 version or later. And please, specify "PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE" with ALL details.
Thanks.

Hi. It's:

# rpm -qa|grep postfix
postfix-2.10.1-6.0.1.el7.centos.x86_64
postfix-perl-scripts-2.10.1-6.0.1.el7.centos.x86_64

Alternative - You can use ip route to set a specific IP for all outgoing connections.

 

[Alxndr.V]

Can you share your main.cf config?
Or at least "inet_interfaces" parameter.
> When inet_interfaces specifies just one IPv4 and/or IPv6 address that is not a loopback address, the Postfix SMTP client will use this address as the IP source address for outbound mail.
> Postfix Configuration Parameters

Cannot reproduce the issue with default settings so need more information here.
