An email security gateway should be able to provide anti-malware scanning, outbound push and pull encryption methods, DLP and some form of intrusion prevention as well as rate control. They should provide clever spam detection techniques such as grey listing, recipient verification, integrate with real-time blacklist sources, BATV functionality, image analysis, dictionaries, integrate with reputation services and more. Most important and the final goal is that spam catch rate should perform well with minimal false positives.
Vendors now provide outbound anti-spam filtering because organisations want to ensure spam and viruses are not sent out from their domain which can get them blacklisted and in all sorts of problems. This can happen intentionally or it can be accidental. A possibility is when a system on the network has been compromised and is sending spam to the outside world using the organisations identity.
Many organisations commit to dedicated spam gateways such as the ones below simply because they are better at detecting spam and much more granular as opposed to UTM appliances. In granularity we mean some dedicated solutions are able to implement very granular content rules such as executable files are only allowed from one specific person to another, per domain and per user quarantine settings, multiple deployment options, built in hard drives for archiving and logging, advanced routing options, integration with Microsoft Outlook so that users can classify an email as spam from the Outlook client and many other powerful and nice to have features.
