Issues Fixed in this Version

GUI: Configuration Report

Collax Server offer the generation of a report about the current server configuration file. The report is generated in the selected language and made available as PDF document.

The generated report contains various details about the server configuration. For instance, the report shows the relation between permissions and the individual elements of permission groups.

Within this release the report is beeing extended and customized to fit the new C-Server release.

E-Mail: Train Spam Filter

Because of an error it was not possible to learn from spam/ham folders with SSL. The e-mail remained in the spam/ham folders. With this update learning works solid.

Net: Wrong Sender IP Address

The Sender-IP can be configured explicitely for routes. If there has been more than one route configured on a device used for connections, this could result in the wrong Sender-IP being used for said connections. This is going to be fixed with this update.

Certificates: Display new certificates

Under “Usage Policy -> Certificates -> X.509 Certificates” you can either generate new certificates or import certificates from the local host via upload. Due to an error in a method for merging arrays, new certificates didn’t show up in the user interface. This issue has been corrected with this update.

Kopano Groupware: hoilday replacement

Due to changed default directives in the Kopano dagent script, a mail loop has been issued. With this Collax software update, the no_double_forward and set_rule_headers options will be set preventing rules to cause a loop.

Misc: system message notification

Important system messages will be sent to the system administrator. The system message of the logfile rotation “gzip: stdin: file size changed while zipping” occured sometimes and worried the system administrator. We fixed the message using a delaycompress option for the logfile rotation process.

Misc: Fax service statistics

The fax service can regularly generate statistics. Due to a wrong permission the statistics have been generated without content. By chaning the owner of the statistics file, the statistics are generated again.

Within this release Multi-Server setup is shown when using a valid license.
