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 6/7: customized the WAF ruleset, scheduled 6 years ago

We noticed that the ModSecurity core rule set was sometimes too restrictive. We have therefore decided to remove the data leak rules (950-954) due to false alarms. These are rules that are intended to prevent an attacker from collecting information about the system, e.g. For example, if PHP code is returned instead of being executed. We have also deactivated the WAF in the backends of the following CMS systems: Neos, TYPO3 and Wordpress to simplify the use of our WAF.

If you notice any problems or have any further questions, do not hesitate to contact us.
