We are looking for someone to configure an AntiSpam-Antivirus Gateway which will protect an external mail server.

We found this article on how it can be done
http://www.thetlog.net/an-anti-spam-gateway/

But since we are not Linux gurus we would like to outsource it to another professional.

the task is that we will provide remote access to our test linux environment, where the vendor will install and configure and inform us on how its done and where we could make modifications.

once the full setup on the test environment is successful then the vendor will re do it (the same setup) on our live production system.

For this project. the vendor has to only setup totally on test environment. for do it again on the live setup, a seperate minimal fee can be charged.
