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.
Kopano Groupware: Kopano and Performance Tuning Paramater
This version will extend and adjust tuning parameters for Kopano. For an optimal tuning, the settings of the MySQL database should be optimized. Especially the values for the innodb_buffer_pool_size will be increased. The innodb_log_file_size will also be restricted to 2048M.
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).

Kopano Groupware: Z-Push: GAB-Sync
The (Global Address Book) GAB-sync script regularly syncronizes the global address book of the Kopano server. Due to an incorrect file system path, the script could not be called and generated an error message. This update adjusts the path and corrects this behavior.
Collax E-Mail Archive: Fix search for recipients
Due to a bad string for searches within the email archive front-end the search query could not be restricted on recipients. This will be fixed with this release, so that all archived emails are displayed again.
Collax E-Mail Archive: Corrected module for mail archive search
Due to a faulty perl-email-address module, not all search queries could be carried out reliably. This will be fixed with this release, so that all archived emails are displayed again.
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.
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.
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.
Kopano Groupware: Database conversion after update 7.1.6
The Kopano database is automatically converted for update 7.1.6 after the server is restarted. This process can, depending on the database size, take between half and several hours. In the dashboard this background task is visible as a job. The Kopano service is not available at the time of conversion. Before the update, make a complete backup of the data. When the conversion is complete, the Kopano service is restarted. Subsequently, further optimizations and schema changes are made. In this time the services Kopano and MySQL may not be stopped.
