I'm not sure when that will exactly take place, but as part of that, they found there was an issue with the DPDK mailing lists doing some header rewriting which will break email bounces via the mailing list to the lab. I think Ali is currently investigating, but I'm sending the email here to make sure you're aware. -Aaron ^ permalink raw reply [flat|nested] 14+ messages in thread

I've attached the raw stuff email. Just to make sure, your example is one that failed, correct? Changing the content / format type will need a little more investigation, just to make sure the change wouldn't break other emails being sent. Does the message content type impact the DMARC evaluation? I thought it was more about headers, routing, and approved mail hosts, etc. Cheers, Lincoln On Wed, Feb 8, 2023 at 4:02 AM Ali Alnubani <alialnu@nvidia.com> wrote: > > -----Original Message----- > > From: Aaron Conole <aconole@redhat.com> > > Sent: Thursday, February 2, 2023 4:42 PM > > To: techboard@dpdk.org > > Cc: Lincoln Lavoie <lylavioe@iol.unh.edu>; ci@dpdk.org > > Subject: UNH - DMARC issue > > > > Hi all, > > > > UNH reported that their IT will be turning on DMARC enforcement "soon." > > I'm not sure when that will exactly take place, but as part of that, > > they found there was an issue with the DPDK mailing lists doing some > > header rewriting which will break email bounces via the mailing list to > > the lab. > > > > I think Ali is currently investigating, but I'm sending the email here > > to make sure you're aware. > > > > -Aaron > > Hello, and apologies for the delay, > > I can confirm that DMARC is failing for some of the reports, but I don't > see obvious mangling to the headers or bodies of these emails. > > Can you please help verify that the list of recipients in To and Cc isn't > being mangled for the reports failing DMARC?
