Nginx and Postfix are not related to each other. So in case Nginx does not start, then you'll have a postfix and a Nginx problem. Did you start from a clean and empty system when you followed the tutorial?
Yes. I just started a new VPS and I started with the tutorial In the Title of this I put Nginx because postfix is installed on ngix server. It's a good ideea to delete postfix and install it again?
I followed this and worked: 1. sudo apt-get purge postfix 2. apt-get -y install postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve dovecot-lmtpd sudo 3.added: -o smtpd_client_restrictions=permit_sasl_authenticated,reject in /etc/postfix/master.cf
If you had ISPConfig already installed, then you'll have to make an ispconfig update with reconfigure services = yes.
