Add-on Software: Virus scanner pattern update

The update mechanism and the status of the virus patterns of all installed and activated virus scanners can be viewed and managed via the menu item “Software - Virus scanner”. At this point, some fixes and improvements were implemented. The display was supplemented to the effect that the used virus scanners, including their usage (Mail, Web or File) and the pattern versioning can be displayed in a table. In addition to the automatic pattern updates these can also be updated manually. A note about the update virus scanner action: If a scanner is not used, the button is now grayed out. Furthermore, the notification in the active monitoring has been corrected so that under certain circumstances was notified of outdated patterns even though the scanner was not or no longer in use.

Notes

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.

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.

E-Mail: Changed ruleset format of Spam Filter SpamAssassin

Please note: On March 1st, the SpamAssassin project will change the format of the ruleset updates. From this date on, only systems that have installed Update 7.1.10 will receive updates.

E-Mail: Retrieving Mail with SSL and validate server certificate

SSL/TLS encryption can used to retrieve e-mail from external e-mail providers. With the SSL-encrypted collection, expired and self-signed certificates are saved and accepted by the server. If this is not desired, the option “Validate server certificates” can be set with this release.

Important: It is recommended to activate and test the setting “Validate server certificate”. In the past it was common to accept expired and self-signed certificates for encrypted collection. This should no longer be necessary and should be avoided.
