The best thing to do with a spammer is report his activity
to his Internet service provider.

   $ host -t mx compodinamic.it
   compodinamic.it mail is handled by 10 mail.register.it.

His registrar forwards his mail. Have they registered an
abuse address with the clearinghouse, or have others reported
usable addresses to it?

   $ whois -h whois.abuse.net register.it
   abuse@dada.it (for register.it)
   postmaster@register.it (for register.it)
   support@register.it (for register.it)
   abuse@register.it (for register.it)
   abuse@inet.it (for register.it)
   abuse@dada.net (for register.it)

Unfortunately, Italian ISPs have not, historically, placed a high
priority on controlling Internet abuse originating on their networks,
as evidenced by the long list of complaint addresses from
the Abuse Clearinghouse for the register.it domain. But a
query of RFC-I returns no evidence that abuse@register.it
*doesn't* work

   $ host -t a register.it.abuse.RFC-Ignorant.org
   Host register.it.abuse.rfc-ignorant.org not found: 3(NXDOMAIN)
      [good response]

   $ host -t a tiscali.net.abuse.rfc-ignorant.org
   tiscali.net.abuse.rfc-ignorant.org has address 127.0.0.4
      [bad response, for comparison]

so you could just forward Mr. Snake Oil's spam, with its
headers intact, to abuse@register.it and they'll remind him
of his obligations under their Acceptable Use Policy.
Save their response, and if he keeps doing it, keep
reporting it. He'll either stop or lose the domain.

Taking their assets away seems to be the only thing
spammers understand. Or maybe they don't understand that
either, but the effect is the same.
