Hi Raul. I believe I can help you. We have hundreds of customers who use SmarterMail and a free anti-spam program we offer called Declude. Also, not trying to sell you anything here, but most of them also use an additional anti-spam program we re-sell called Message Sniffer from the company Arm Research. If you are interested, I will be happy to install and set up Declude free of charge on your server (we usually charge $75 for the install and setup) and I will also give you a free 30 day, fully functioning trial of Message Sniffer with NO obligation to buy. I'm sure you will be pleased with the results. If you are interested, please email me directly at the address in my signature. Thanks!
