LiveConfig v2.16

We are happy to announce the availability of LiveConfig 2.16!

Support for Debian 12 (“Bookworm”)

The next version of Debian will be released on June 10, 2023. LiveConfig 2.16 already supports Debian 12, and we have provided a guide to Update from Debian 11 to Debian 12.

More privacy in email headers

In the headers of emails, the transport path is usually recorded - i.e., which server received the email from whom. Sending an email is also recorded there - and thus usually the IP address of the device with which the email was sent:

Received: from <Gerätename> (<Netzwerkname> [<IP-Adresse>])
  by <Mailserver-Name> (Postfix) with ESMTPA id 067F340327;
  Mon, 22 May 2023 12:26:26 +0200 (CEST)

Many of this information (device name, network name, and IP address of the device) should actually not be included in an email as it can allow conclusions to be drawn about the sender’s infrastructure.

With LiveConfig 2.16, there is the possibility to filter out this information from sent emails (Server Management -> Email -> Postfix settings, option “Hide SMTP sender’s IP address”). This affects all emails that are sent via port 587 (Submission) or 465 (SMTPS) - with port 25 this is technically not possible.

The Received header will then look like this:

Received: by <Mailserver-Name> (Postfix) with ESMTPA id 067F340327;
  Mon, 22 May 2023 12:26:26 +0200 (CEST)

The complete list of all changes can be found as always in the changelog.

You can install the update as usual via the package manager of your distribution:

• Debian/Ubuntu: apt update && apt upgrade
• CentOS/RHEL: yum update
