Hi Since a couple of days, we get a increased number of complaints from customer receiving duplicate emails.
Emails duplicated (sometimes sent 5 or more times within a couple of hours) are all sent from outlook.com. I start to suspect, that there might be a DNS issue causing delayed or failed lookups with our DKIM / DMARC Milter, as my logs hint to large delays while they run. When I try to look up the records manually I can not reproduce. Has anyone observed similar issues and has been able to pinpoint the cause?
