Postfix / Centos7 - Postfix 3.4.7 version 3.8.1 upgrade?

« on: June 29, 2023, 06:48:35 PM »

I am running the following code over ssh. postconf mail_version

the result shows mail_version = 3.4.7 as i understand this is the postfix version..

I want to upgrade to Postfix 3.8.1. The postfix-3.8.1.tar.gz file exists. How can I upgrade this version now?

Can you please explain in detail

Hello,

I've looked at the same threads on the forum. But my problem is this. If you pay attention to the logs, the same IP is always trying to establish a connection. Firewall active, banned in csf.conf in 2 attempts. But it doesn't ban, where am I going wrong
