This product provides a content-filtering SMTP gateway on the Windows 2000/2003 Server operating system. It can share a server with other applications, but a dedicated server is recommended. It is available as a plug-in for Microsoft Exchange 5.5 and 2000, which can then police internal emails. It has open relay protection.
Security has been the mainstay of SurfControl's business for quite some time, so it is no surprise to see an email security solution. A policy-based application, SurfControl E-mail Filter is actually an SMTP host through which all mail is diverted.
Installation is amazingly simple. It's just a matter of entering the required information into a few windows and telling the product where it sits in relation to the email server. For reasons of economy, it can be installed on the same machine as the mail server, but for reasons of reliability this isn't recommended.
