When receiving and decrypting a 5MB email, the email is rejected and the error “ASN1 not enough memory” is displayed. The same error is also displayed in message tracking.
This problem occurs because a buffer size is not properly increased by the .NET framework. This problem is known to Microsoft and can be fixed with the hotfix below.
To resolve this problem, install the following Microsoft hotfix: http://support.microsoft.com/kb/2480994/de
When updating from version 9.0 to version 9.1 or 9.2, all settings and user information are retained during the update.
When upgrading to version 9.0, the subdivision into the new areas Monitoring, People and Identities and Configuration is immediately noticeable. For each of these areas, users can be explicitly allowed access via security groups. This means that you can assign the rights to a person in your company, e.g. to only use the Monitoring area. This person would then have no access to People and Identities or Configuration. The installation program of the Net at Work Mail Gateway automatically makes the user logged on during the installation a member of all three groups.
The security groups mentioned above are explained in more detail below.
Members of this user group may use the Monitoring area. This area displays email statistics, email queues, or key figures about the performance of your server.
Members of this user group may use the People and Identities area. This area manages internal and external communication partners and their cryptographic keys.
Members of this user group may use the Configuration area. This area contains the settings of the Net at Work Mail Gateway and its gateway roles, such as connectors, rules, notifications, and connections to other systems.
The new structure consistently combines previously redundant configuration settings and enables task-oriented administration. This means that the management console of version 9.0 no longer focuses on the roles of the Net at Work Mail Gateway, but on the task you have to perform.
This allowed many areas to be merged and simplified. An example: The address rewriting area of version 8.5 had to be configured to match the local users and their email addresses. The address transcriptions have now been moved to the email addresses of the local users, so that the assignment between email addresses and address transcriptions is made automatically.
Finally, the Commtouch service has been renamed to CYREN. CYREN continues to provide you with a high level of service.
Warning
An upgrade to version 9.0 is currently only supported by version 8.5.
Some changes of version 9.0 have a strong effect on the installation of the update. This is the replication of all configuration data between the intranet role and the connected gateway roles. In particular, installations with more than one gateway role must be updated to version 9.0 with great care.
Furthermore, the roles “Reporting Role” and “UserManagement Role” have been combined and are now managed as “Intranet Role”. The new Intranet role will continue to work with the previous database of the UserManagement role. This database will be extended by the update by the tables of the previous reporting role.
In the previous versions, a separate certificate with the name of the service was created for each service and used for the connection between the individual roles. Since version 9.0, a certificate with the server name is created in the CN.
Please note
If you use a custom MSC file instead of the Management Console (MSC file) shortcut created by Setup, this file may not work after the upgrade and the interface may display errors. In this case, please delete your custom MSC file and recreate it.
When updating from version 8.0 to version 8.5, all settings and user information are retained during the update.
