Version 3 Architecture

How do I set up my mail server and Message Sniffer on different servers?

At the moment SNFServer and SNFClient need to run on the same box. SNFClient calls the SNFServer via localhost TCP. SNFServer processes the message as a file on the local file system.

If you want to run SNF on a gateway then that gateway must run some software to process the email going through that gateway - either an SMTP proxy like eWall, or an actual SMTP server connected to SNF such as a postfix on a *nix box. There are many options for gateway solutions - the choice depends upon your needs.
