New in this Version

New Add-on module - Collax Central

With this version, the new add-on module “Collax Central” is available. It helps to keep track of all Collax servers, making administration easier and points out early on emerging problems. The Collax Central Dashboard is a tool to make the administration efficient and the place where all the threads come together. This can be problems to be recognized at a glance in a large server landscape. Sporadic and regular maintenance tasks go quickly by the hand. Collax Central is available as a module for the Collax C servers (eg Collax Business Server). If you are interested, please contact your dealer, distributor or Collax distributor.

VPN: Distribution of CRLs via OCSP or CRL URL

Previously, CRLs had to be individually and with each change by exporting and importing to the respective servers be distributed. With the new options OCSP URL and CRL URL the CRLs can be distributed automatically. Either an existing network OCSP server can be used or a CRL URL will be generated and configured together with the certificates on the participating servers. Currently this function is supported only by the local service for IPSec VPN (IKEv1, IKEv2).

Collax Advanced Networking: Brute Force Protection: Status

In the brute force protection status dialog, blocked IP addresses are listed. This dialog is located under Status / Maintenance -> Status -> Brute Force Protection Status. Under certain circumstances, the call could result in a timeout. This behavior is fixed within this update.

VPN: VPN connection after certificate update

The VPN component Charon has shown unexpected behavior and VPN connections with a certificate renewed by Let’s Encrypt have not been reloaded, causing the connection not to establish anymore. This update will provide the renewed certificate for the link to be reread again.

System Management: Amavis - Recipient notification

AMaViS (A Mail Virus Scanner) is a high-performance and reliable interface between the mailer (MTA) and one or more virus scanners. If infected or unverifiable messages can be detected, it can be controlled, whether the recipient receives a warning via e-mail. Due to an error in the configuration file Amavis has set the sender domain of the recipient notification incorrectly, causing certain e-mail servers not to address the message. This will be fixed with this release.


E-Mail: Avira AntiVir prior Version 7.1.6

From Avira, an automatic update of the core components of Avira has been carried out. In this context, a new dependency of the libraries has been added, the next time the virus scanner is not started can be resolved. The result is that the virus scanner does not work during a reboot or configuration change is restarted. For security reasons, emails will no longer be delivered. To solve the problem, please update your server to version 7.1.6. Note: As long as the virus scanner is not restarted, it works in its entirety.
