	echo ROUNDCUBE_DES_KEY=$(openssl rand -base64 24) &gt;&gt; ~/docker/iRedMail/iredmail-docker.conf<br />
	# output the conf file and verify the values<br />
	cat ~/docker/iRedMail/iredmail-docker.conf<br />
	# set owner of working directories<br />
	sudo chown &quot;$USER&quot;:&quot;$USER&quot; ~/docker -R<br />
