It was a few years ago, so no longer have the logs. The outage was around 30 minutes (which I still consider a short time) and even after a few weeks, the emails didn't appear. I no longer have this issue as I have 2 MXs in different datacenters. I am also not willing to disable both MXs to see if this still occurs. -- Joost
