Space before comma in postfix master configuration file at smtpd_client_restrictions

Summary

When master.cf for postfix is created/written by the update or install script the line

smtpd_client_restrictions

will have a space after

reject_unauth_pipelining

and not directly the comma

Steps to reproduce

1. Running ispconfig_update

Correct behaviour

There should not be a space before the comma.

Environment

Server OS + version: Debian 12
ISPConfig version: 3.2.12

Proposed fix

I will create a merge request.
