So an anti-spam system requires constant maintenance and tuning to provide satisfactory performance continuously. This calls for a managed anti-spam system instead of device-based approaches.

Linuxense provides ``Managed Anti-spam services'' to ISPs and other service providers with large number of email accounts. There are three types of managed services available to choose from:

1. Dedicated Anti-spam system-Leased: In this service, you do not have to provide any servers. You can lease them from us. This is the fastest option to go live if you are service provider.
2. Dedicated Anti-spam system-Owned: Same as above. The difference is that you need to provide the hardware required to set up the anti-spam system.
3. Shared Anti-spam system: This option is popular among enterprises and other organisations for filtering their own emails.

To start using the Managed Anti-Spam service Linuxense, there is no need to make any changes in your current email infrastructure; re-point your MX records to the anti-spam servers and it will start working. This is as simple as that for the all three types of anti-spam services.

Linuxense has already provided this solution to various types of customers ranging from small business to large organizations to to ISPs. The single largest installation handles one-and-a-half million emails per day with 99% effectiveness.
