  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

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.
 
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.
