Re: many spam from libero.it
I am seeing that libero.it has an MX.
Non-authoritative answer:
libero.it MX preference = 10, mail exchanger = liberomx1.libero.it
libero.it MX preference = 10, mail exchanger = liberomx3.libero.it
libero.it MX preference = 10, mail exchanger = liberomx4.libero.it
libero.it MX preference = 10, mail exchanger = liberomx2.libero.it
So your smtpd_helo_restrictions will not reject these messages. You'll need to probably blacklist this source.
