Note
Medium Risk
Build-time change that enables additional mail-authentication code paths; risk is primarily around new dependencies/behavior in ARC processing and potential interoperability issues.
Overview
Enables Exim’s experimental ARC (Authenticated Received Chain) support at build time by uncommenting
EXPERIMENTAL_ARC=yesinsrc/src/EDITME, so ARC verification/signing code is compiled in (alongside existing SPF/DKIM requirements).Written by Cursor Bugbot for commit 3d8793a. This will update automatically on new commits. Configure here.
