Spam has rapidly turned from a mere nuisance into a major security threat and financial drain for organizations worldwide. While at first spam was relatively easy to block through the use of blacklists or basic content filtering techniques, spamming methods have advanced to the point that  these  technologies  are no  longer sufficient or cost-effective. The financial    costs      associated     with     spam

are also large and growing. Therefore, with such an influx of unwanted, dangerous junk mail, it is necessary for organizations to broaden the efforts at combating spam by applying a new generation of anti-spam solutions that leverage multiple layers of protection, including maintenance services. After years of R&D, aamra networks has designed an anti-spam solution named NOSPAM, suitable for small to large enterprises.
