  More precisely, you weren't aware of a problem, which is not
  necessarily the same thing.

  This isn't a zone, as it's not delegated; it's just a host, as can
  be seen by requesting relevant DNS resource records from one of the
  servers (ns{1,2}.virtualbit.it) responsible for the zone
  granellodisenape.org.

  Where your new server fits in all of this isn't clear, as you don't
  mention what either its name or its address is.

  It may be useful for you to use a public validation service (such as
  http://zonemaster.net/) to check the name service for your zone.

  From where I sit, this problem does not appear.

  If you can confirm that this problem is still present, you'll need
  to look for help with analysing it to someone who has access to the
  name server(s) used by this SMTP server.  Either of the users you
  mention may be able to help.
