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 Version 5: fix Letsencrypt dependency problem

It was not possible to activate Letsencrypt on a already existing websites under some circumstances. We where finally able to reproduce and fix this problem for good.

Closes #335

Managed Server Version 5: Redis service added

By now, we used Redis by installing redis-server through base::packages. This works fine as long as Redis is not considered a important part of your setup. As we have a project where Redis is becoming important more and more, we implemented the redis service, which will not only install redis, but also make sure the daemon is running and the service is monitored locally through Monit and in our global monitoring as well.

For current setups, no change is required, however we will approach all affected customers over the next few days to explain this change in more detail.

Closes #333
