Postfix not working

[Francesco]

Hi, after installed EHCP version last you realised on ubuntu 16.04, I can't use Postfix to send mail to other destination with this answer:
<blockquote>NOQUEUE: reject: RCPT from XX-XX-XX-XXX.ip152.fastwebnet.it[XX.XX.XXX.XXX]: 554 5.7.1 <maildiesempio@gmail.com>: Relay access denied; from=<nome .cognome@dominiosuserver.it> to=<maildiesempio@gmail.com> proto=ESMTP helo=<PCdiXX></blockquote>

This is postconf -n
