SETUP REQUIREMENTS
Local Cloud
Hardware
Depending on the load/traffic of the domains that will be added to the system, different hardware requirements apply. The following recommendations for an installation of a SpamExperts Local Cloud are based on:
•
Average of 10 active email users per domain•
Average email usage•
Average attachment size•
Average traffic shapeIf your domains and traffic differ significantly from these averages, other hardware specifications may be more suitable. The table serves as a rough overview.
Notes
•
Hard disk: the faster the “writes” of your hard disk are, the more email can be processed with your servers. Fastwrites are beneficial for the logging of connections.
•
Virtualization: servers can optionally be virtualized (VMWare, KVM, Xen, OpenVZ, Hyper-V, Virtuozzo, etc.).•
Root access: for the installation to work smoothly, we need direct root access to the default port (customers keeproot access too but should no access it unless absolutely necessary).
•
Software management: SpamExperts will take full care of the software management on the cluster and customersshould not change the configuration of the software.

Server Set-Up
Round Robin
In a Round Robin setup, both the primary and fallback MX-record point to a host name that has multiple A-records. The host name of the primary MX-record has A-records to the primary IP(s). The host name of the fallback MX-record has A-records to the fallback IP(s).
The servers themselves need separate host names (different from the MX-records) for update and maintenance purposes. An example is shown below. To optimally use the available resources, SpamExperts recommends a parallel setup for the filtering servers. Each server in this setup acts both as a primary and fallback server, which implies:
•
One host name per server•
2 IP addresses per server•
2 A-records per server•
2 MX-recordsLoad balanced
In a load balanced system, the primary MX-record hostname resolves to the load balancer primary IP, the fallback MX-record to the fallback IP. The load balancer then distributes the traffic evenly to the filter-cluster IPs.
Classical primary/fallback
In a classical primary fallback setup, the primary MX-record points to the primary server IP of the filter-cluster and the secondary IP points to the fallback IP of the filter-cluster. In such set-up, the primary server will have to handle most of the load alone and the fallback only becomes active in times of high load.
Operating System Requirements
Linux Debian
The standard installation required on all (optionally virtual) servers is:
•
Linux Debian 6.0 “Squeeze” 32/64-bit (minimal installation, core & standard system only)•
Default partitioning (all files in one partition)•
Swap partition (this is the default)•
No (security) changes to the default configurationDebian is a very straightforward system. Even if you are not familiar with it, you should be capable of installing it without any problems.
