How does it work? The filter is a gateway device. The email is sent to the filter first. The filter scans for viruses and then checks to determine if the email is spam. If the email is clean and not spam it forwards it to the email server. This process allows the email server to be invisible on the internet. No email is sent directly to the email server without being filtered first.
