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:[email protected], mailto:[email protected]\; " 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. -- Chris Adams <[email protected]> -- devel mailing list [email protected] https://lists.fedoraproject.org/admin/lists/[email protected]
