SNF does not integrate directly with MailEnable nor Exchange.

The best way to use SNF on MailEnable is using MXScan. They are one of our resellers so you not
only get MXScan and expert assistance, but also a great price on SNF from them.

Dakota Software offers a product for Exchange as well as a plugin to integrate Message Sniffer.

In order to minimize complexity, it is often better to do filtering in front of Exchange instead of integrating it with Exchange. This approach also helps to keep Exchange working quickly and more efficiently since it reduces the system's workload. There are a number of ways to do this with SNF including some that are free such as integrating SNF with postfix on a linux box, or
using the "community edition" of some Windows based solutions with SNF.
