Issues Fixed in this Version

E-Mail: Filtering E-Mails globally and per Domain

If e-mails were fetched via POP3 or IMAP from external servers, e-mails are delivered directly as user@FQDN. In this case e-mails can be filtered only if the option Global mail filter was set. If this option was not set, but was substituted with selective filtering per e-mail domain, e-mails hadn’t been neither stored into e-mail archives nor filtered on Spam or viruses. From this update the option Global mail filter needs to be set to archive e-mails or to filter fetched e-mails on Spam and viruses. If at least one of both functions is used, the update sets the option Global mail filter automatically.

File: Web access and File Share Access

In the Collax Webaccess file share can be accessed via a browser. Under circumstances access to file shares via webaccess was not possible any more. From this update the webaccess authorisations are corrected in relation on file shares which the authorised group may read or write.

Collax E-Mail Archive: Size of a DVD-5 ISO File

With the E-Mail Archive all in- and outgoing e-mails can be stored into archives. Afterwards archive volumes can be burnt on CD, DVD or Blu-Ray. The ISO file size for DVD-5 was given wrong, so these ISO files could not be burnt on 4.7 GB DVD medias. With this update ISO file size is calculated correctly for DVD-5, archiv volumes can be burnt on a 4.7 GB DVD media. Archiv volumes which ISO file size is up to now greater than 4.7 GB, can be burnt alternatively on DVD-9 or DVD-10 media.

Security: ClamAV

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 0.96.

After updating and the automatically reboot of your Collax Server you have to do a manual pattern update under Settings->Filter->Virus Scanner->ClamAV.

Backup/Restore: USB Backup Targets

If an USB device should be setup as a backup target, the warning diskid:The object does not exist was displayed under certain circumstances and the USB device could not be used as backup target. This error is repaired with this update, USB devices can be set up as backup targets.

System Management: E-Mail Notification of Admin Login

Collax server inform the administrator about various events via e-mail. Under circumstances the notification could fail if the login on the administration gui is performed. This issue is repaired with this update.

System Management: Delegated Administrator can not manage all Forms

Administration roles are used to delegate individual rights to users who shall administer the system. Under circumstances not all forms were displayed in the GUI whithin such deligated administration. With this update the display of refered administration forms is corrected for users who are delegated for system administration.

Misc: Backup of Zarafa locks E-Mail Ttraffic

During a backup of the Zarafa database no e-mails could be processed by the Zarafa server. From this update the backup of the Zarafa database is optimised by the option –single-transaction. E-mails can be thereby processed by the Zarafa server during a backup.

Misc: Zarafa caused high System Load

Zarafa Groupware can swap e-mail attachments from the database into the file system. Up to now the calculation of the necessary size for swapping was executed by the call of the configuration form Mail and Messaging -> Zarafa Groupware -> Configuration as well as when doing a configuration activation. and led to a high system load. This is corrected with this update, now the calculation takes place exclusively before deleting attachements from the database.

The Anti Virus product Avira Antivir will now be identically licensed like all Collax Modules. With this method a higher handling comfort is reached.
