I had recently updated my K8s cluster and was seeing weird issues with DMS. I traced it down to a missing `MAC_OVERRIDE` capability. TBH I do not fully understand _why_ this capability is required, but it wasn't working for me in K8s 1.35.0 without it.

- Originally created by @tomav, this project is now maintained by volunteers since January 2021.
Tip
Be sure to read our documentation. It provides guidance on initial setup of your mail server.
Important
If you have issues, please search through the documentation for your version before opening an issue.
The issue tracker is for issues, not for personal support.
