This is an experiment DON'T use it on production

• Copy each template fragment to its location under templates-custom, as reported in the comment
• Edit each file replacing its contents with your site setup
• To re-configure Postfix, execute the following commands:

  
  
  expand-template /etc/postfix/relaymaps
  
  signal-event nethserver-mail-common-save
