Hello all, if you specify a non default "config_directory" variable when using "postfix-install" script, you'll have this error : "postfix: fatal: open /etc/postfix/main.cf: No such file or directory"
To solve it, in the last line of "postfix-install", replace : "bin/postfix post-install $post_install_options || exit 1" by "bin/postfix -c $CONFIG_DIRECTORY post-install $post_install_options || exit 1" Regards, Matthieu.
