Hello @Fulvio Bordiglia
Welcome to the Atlassian community.
First, this is a publicly accessible forum. It is a very bad idea to post your email address in a public forum. Anybody can read this information and you could end up getting lots of junk email.
Second, what is the issue with which you need help?
Third, what is the product and hosting type? Is it Jira Software or Jira Service Management? Is it the Cloud (software-as-a-service) deployment managed by Atlassian, or is it Data Center (self-hosted) managed by you or your company?
Fourth, are you using an environment where you have a current, paid subscription?
And lastly, are you a Jira or Site Administrator for the the instance?
