Yes. Like I said earlier, the problem is DMARC, which is based on
the
header From: address. libero.it has the following DMARC policy
record:
"v=DMARC1\; p=quarantine\; rua= mailto:dmarc_agg_rep@libero.it,
mailto:dmarc_agg@auth.returnpath.net\; "
Hi, I setup my email with DMARC yesterday reading "How to Setup DMARC
records in cPanel" [1] , and check today with
http://www.mail-tester.com/
Seems common mail servers don't setup DMARC records in dns, it OT but
it may help improve mail servers.

So, their policy says that non-conforming messages should be
quarantined
by receivers of those messages. Mailing lists that don't rewrite the
header From: address will cause messages from domains with DMARC
policies of quarantine or reject to be a problem for mail servers
that
apply DMARC policies.
