Mailcow: Changes to Email Alias Forwarding

To improve email deliverability, we will restrict email aliases from forwarding messages to external domains.

Why this change?

Forwarding emails to external providers can cause authentication issues (particularly SPF), resulting in messages being rejected or classified as spam.

What does this mean?

  • Existing aliases will continue to work as usual, unless modified.
  • Forwarding to locally hosted domains remains unaffected.
  • Creating or modifying aliases to forward to external domains will be restricted.
  • External forwarding will remain possible through an alternative method.

For instructions, please see our forwarding guide.

If you have any questions, do not hesitate to contact us.

Managed Server 7/8: Filesystem Size Changes, scheduled 3 years ago

Up to now, our managed servers did use a large, virtual file system, and the actual space assigned was just a value checked within our monitoring. As this has some storage related drawbacks, we will change the behavior today. As of now, the file system size will be set to the value selected in Cockpit, plus an added buffer of 30 percent. Changes are still possible without reboot, and all tools and checks do reflect the new behavior already. We will monitor the rollout for each system carefully, and do not expect any noticeable changes apart from the new file system total size.
