Only in installations with a large number of users and unusual requirements can adjustments lead to better performance. Changes should only be made by experienced administrators or on the recommendation of support. The section is divided into three parts. The values for the MySQL server and the storage engines MyISAM and InnoDB can be configured. If a field remains empty, the default value is used. The names of the fields are linked and lead to the documentation of the respective value.

When using Kopano, it is possible to set up folders to which all users have shared access on the mail server. They can also be addressed by e-mail and also be chosen as the sender address for e-mails.

VPN connection with revoked certificates
The VPN component charon has shown unexpected behavior and VPN connections with a certificate revoked by a CRL. With this update prevents VPN tunnels from being set up with revoked certificates. Existing VPN tunnels remain active until the next re-keying (default: 9 hours).
Certificates: Certificate Creation
Certificates can be added under “Usage Policy -> X.509 Certificates”. Due to an error, user-type certificates were generated incorrectly. The certificate purpose was in this case “SSL client: No” instead of “SSL client: Yes”. This is fixed with this update. Furthermore, under certain circumstances, certificates could not be generated in every key length. This is also fixed. This update also generates an error message if the entered CA password is wrong.
