    Any time Plesk updates /etc/postfix/main.cf, it will set inet_protocols = all.  If you choose to change this setting to inet_protocols = ipv4 , you also need to monitor any change Plesk makes to /etc/postfix/main.cf.  When Plesk makes a change to main.cf, it will change the setting back to inet_protocols = all.  It is your responsibility to know Plesk changed /etc/postfix/main.cf so you can reapply setting inet_protocols = ipv4 after each Plesk update.

    Hello Greg,

    I have attempted to reproduce the reported behavior on Plesk Onyx (CentOS 6), however, 'inet_protocols' parameter stays unchanged after changing mail server settings via Plesk.

    Could you please shed some light on the issue and let us know:

    1. Plesk version and OS you are using.

    2. Actions with Postfix that result in 'inet_protocols' parameter changing.

    Thank s in advance!

    We are using Plesk 12.5 on CentOS 7.  We monitor changes in main.cf to ensure when Plesk overrides we can adjust according.  Please run 

    plesk repair mail -y -v

    and watch changes in /etc/postfix/main.cf.  Please also see internal support ticket 21903 for other data that is changed Postfix configuration by Plesk when this command is run. Would it be possible to document what is changed and what is not based on input from developers?
