If you are interested, please provide us your domainname and destination MX server. We then add this to our MX service, and you will not receive spam anymore once you have changed your DNS settings to point to our MX records.
If you like the service, it is possible to offer it as a premium service to your customers. Furthermore there are possibilities to get a dedicated SpamExperts MX filter server in your own network.
We have been developing our own technologies the last year. For quite some time now, we have the SpamExperts Home download software online (for free). Success rates are always hard to provide. Every situation is different. Of course I can give you some nice marketing numbers but they can never really be accurate. I'd like to invite you to test and experience it yourself. That's the only true way to show accuracy of any product.
