New in this Version
Collax Let’s Encrypt: New Add-on module - Let’s Encrypt
With this version, the new add-on module “Collax Let’s Encrypt” is available. Let’s Encrypt is a certification authority offering free X.509 certificates for SSL encryption.
The usual manual processes are simplified by an automated process. The CA of the Let’s Encrypt certificates is a preinstalled, trusted root certification authority of all common web browsers. Thus, browsers do not report a warning or an error encrypting web pages with a Let’s Encrypt certificate. Let’s-Encrypt certificates are primarily intended for the encryption of web pages. But they can also be used for other purposes.
Let’s-Encrypt certificates are valid for 90 days. They can be renewed as often as you like. The renewal process is performed automatically by the Collax Server. A certificate will be renewed 30 days before expiration. The expired certificates are automatically exchanged for the new ones.
GUI: System Information
Collax servers offer extensive possibilities to analyze the entire system. For this purpose, a lot of information is provided: in the left menu area is a section about system information and system usage of the product. With scaled view of the web browser, especially at high monitor resolutions, this could lead to not all sections beeing displayed. This will be adjusted with this update, so that the menu boxes can be displayed even at high zoom rates.
E-Mail: Redirect MIME filtered email to email-address
Under the dialogue “Mail -> Mail Security -> Headers / MIME Filter” you can define your own rules to filter e-mail attachments. It can both be filtered on the file extension as well as being filtered to the MIME content type. So far there were several options as an action for the MIME filter. With this release the new action “Redirect” has been added. If “Redirect” is chosen, the filtered e-mail can be redirected to an individual e-mail address. Per-plus addressing, it can also be redirected directly into an IMAP folder, e.g. “+public.oeffentlicherfolder@FQDN”.
From this version StrongSwan 5.6.3 is going to be implemented.
IPsec user authentication IKEv2
For a link of type “IPsec VPN” can be specified which method for user authentication should be used. From this version IKEv2 is available as an authentication method.
System Management: Linux Kernel 4.9.112
This update installs Linux kernel 4.9.112.
System Management: Proper status emails
With this update, notifications will be sent to the e-mail address of the system owner adapted for the service fcron. The package is responsible for timed, recurrent processes, such as the update status of virus scanners. On the one hand, the status is displayed in the subject line and a distinction is made whether it succeeds or was faulty. Second, the description within the subject becomes more understandable formulated (human readable) and it is directly apparent from which server the status mails are sent.
Issues Fixed in this Version
In the source code of the virus scanner ClamAV security holes have been discovered. These holes will be closed within this software update to the version 0.100.1.
GUI: Focus on input fields
Due to a behavior change within the framework for the presentation of the administration interface, input fields had to be clicked twice during the view in the firefox web browser for beeing focussed. This will be corrected with this update.
E-Mail: SIEVE and Web Mail
Due to an encoding error in the cyrus IMAP service, the message subject of vacation notes became unreadable. This release fixes this behaviour.
E-Mail: Postmaster notification for oversized messages
In the SMTP Receive section, the maximum size of an e-mail can be specified. In the source code of the e-mail retrieval program fetchmail, errors have been corrected, because when fetching emails with oversize, no notification of the postmaster took place. With this release, this behavior is resolved. For newly received oversized emails, the postmaster becomes immediately and then every 8 hours informed, that the email could not be picked
Security: Collax Anti Spam phraselist
The Collax Anti Spam feature powered by Kaspersky ™ includes a number of new and current applications that guarantee the security of e-mail servers. To the methods Collax Anti Spam includes phrasekists that contain phrases that are considered spam or not recognized as spam (blacklist / whitelist). Due to a validation error within the input field in the graphical user interface, certain UTF8 coded phrase lists are not filtered (including umlauts). This release fixes this behavior.
Kopano Groupware: Orphaned resources
With the help of resources it is very easy to manage and check whether meeting rooms, projectors or other facilities and items for appointments are available. Due to an error in the program code it could possibly lead to resources have been marked as orphaned. This will be corrected with this update.
Incorrect inheritance of rules from parent network groups
The firewall matrix provides a unique visual representation of regulated network connections. The configuration of an explicit rule with the default “Apply” without further specific service rules led to a faulty firewall configuration. As expected, the same configuration will now be created with this update as if no rule was specified.
System Management: New syntax for NSClient++ configfile
With this update, configuration files for Collax Server that are appropriate for NSClient ++ will be adapted for the the current syntax. NSClient ++ is an NRPE (Nagios) Agent for Windows. Therefore hosts can be used to specify the services to be monitored for their functionality.
E-Mail: Increased required space when using IMAP and full-text index
The option “Generate full-text index” in the options of the dialog “Mail and Messaging -> Mail Storage -> IMAP and POP3” generates a full-text index of the local IMAP folders which accelerates the search within the IMAP folders and e-mails. While activated, the system could use up to 20% more space compared to the former release (also with activated index) for the service cyrus. Please check the space requirements of the service cyrus in advance. Under the dialog “Status -> System -> Statistics” the graph “filesystem/data” shows further details.

E-Mail: Release already deleted emails in IMAP mailboxes
In the dialog “Mail and Messaging -> Mail Storage -> IMAP and POP3” the IMAP server can be activated for the users to get access to their IMAP mailboxes. Due to a modified standard directive within the Cyrus IMAP mail server since the release V7, e-mails already deleted by the mail client have not been completely released from the harddisc. Since release 7.0.22, cyr_expire will free up memory for already deleted emails. Please note that already after restarting the IMAP service during the update, the process is started and proceeded after restarting the server and thus start the IMAP service.
