Hey all -- Haven't heard from Microsoft contacts about this, so thought to ask here.
Has anyone else here experienced DKIM failing at O365 due to "compauth"?.... as well as passing with the same exact message/authentication in another test? :/ I've received a few different codes, but the most recent is `compauth=fail reason=001`. I've read all about the measure put forth by Microsoft but nothing I've read should cause any failure as authentication is correctly inputted and this isn't failing at any other mailbox. There's some theory around List-Unsubscribe causing this, but I'm not fully buying that yet based on a battery of tests. Certainly could, but not seeing why/how it would at the moment. I'm really scratching my head on this one. I have a plethora of full headers but did not want to inundate that with this original post, as there's not just one sending domain / example. If anyone has experienced this, I'd love to hear about it. If you'd like to post here or DM me at dickie.lafla...@oracle.com <mailto:dickie.lafla...@oracle.com>, super appreciate any thoughts. Thanks! Dickie LaFlamme Senior Deliverability Specialist | Oracle-Dyn
