To stop someone sending emails in your company's name you configure SPF, DKIM and DMARC in the domain's DNS and check who is authorised to send. No measure removes the risk entirely, but it makes forgery much harder.
Companies between Cantù, Como and Milan that send invoices or payment details by email are frequent targets. To find out more about protecting your domain, see domains, email and servers.
