A colleague who uses gmail for his MUA has been complaining for some time that he never gets Launchpad notification emails for comments that I make on his bug reports and merge requests, but he does get them from other team members. It's now clear to me having found this bug report that this Launchpad behavior is the reason for that problem. My employer publishes a strict DMARC policy (p=reject), whereas the other people he interacts with through Launchpad have either a lenient DMARC policy (p=none) or don't configure DMARC at all.
