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: Website Service: Enable ModSecurity in DetectionOnly Mode

So far, there was no web application firewall on generation 6 servers, as we had yet to lay some groundwork before. With this change, we will enable ModSecurity and load the OWASP core set, please see the detailed changes below:

  • update nginx to the latest stable version 1.14.2
  • load ModSecurity base configuration
  • load OWASP core rule set
  • enable ModSecurity in DetectionOnly mode (= logging only)
  • detected requests are logged into the ModSecurity audit log at /var/log/nginx/modsecurity.log (accessible via devop user)

Next steps:

  • we will analyze all audit logs and take appropriate actions if required
  • we might contact you over the next 2 weeks to discuss required changes on our or your end if required
  • we're going to activate blocking mode (switch engine from DetectionOnly to on) on Monday, January 28th
