For a no-obligation 30-day FREE trial of the Death2Spam Managed Service Solution for Small-Medium Business, simply enter your domain name and the administrator's email address to receive information about configuring the Mail Exchanger (MX) records for filtering your domain...    

Completing this wizard configures the D2S server so that it's able to relay email messages on to your domain after scanning for viruses, porn and spam.

After completing this wizard, you will need to contact your ISP or DNS provider, and request that a new MX record be created for your domain. This change is very easily reverted if, for any reason, you do not wish to continue with the trial.
