cPanel is introducing new experimental support for ARC (Authenticated Received Chain) for forwarded messages and mailing lists, to comply with Google\u2019s recent email authentication requirements. This update is crucial for ensuring uninterrupted email communication for our customers using mailing lists and forwarded emails. <\/p>\n\n\n\n

ARC is an authentication method designed to verify the legitimacy of forwarded emails and emails sent from mailing lists. Acting as a digital signature, ARC adds three message headers to an email: authentication results, a message signature, and a seal header. <\/p>\n\n\n\n

By implementing ARC, Google aims to enhance email security and prevent spam and phishing attacks. Emails sent to Google without ARC are at risk of being marked as spam or rejected entirely, significantly impacting deliverability and communication reliability. <\/p>\n\n\n\n

For more information about Google and ARC specifically, please refer to Google\u2019s documentation<\/a>. <\/p>\n\n\n\n

Impact on cPanel & WHM<\/h2>\n\n\n\n

To maintain seamless email functionality for our users, we integrated experimental support of ARC into cPanel v122. This update ensures that your emails reach their intended recipients without issue. <\/p>\n\n\n\n

Currently cPanel & WHM\u2019s experimental ARC support only applies to outbound headers. <\/p>\n\n\n\n

Please note:<\/strong> ARC is NOT ENABLED by default. Both DKIM and SPF must be enabled to use ARC. Review our documentation to make sure those DNS records are set up for your domains:<\/p>\n\n\n\n
