Murray, We’ve started (relatively recently, in volume) logging ARC data so we can try to make some informed decisions going forward. We’re not yet acting on anything as a result, nor writing into the message. We’re also not doing anything when mail is being forwarded. We’ll hopefully have more information/data available to share in the future (may not be the very near future given other projects going on). This isn’t a guarantee that we’ll fully adopt ARC in the future, but enough to say we’re logging/analyzing things.
Random thing while looking at some data just now .. At least one message apparently came through with seven ARC sets. Let me know if there’s anything I can answer at this point. -- Alex Brotman Sr. Engineer, Anti-Abuse & Messaging Policy Comcast From: dmarc <[email protected]> On Behalf Of Murray S.
