We just did a nice upgrade to our Ninja email security product — it now includes disclaimer functionality built-in. This makes Ninja a ridiculous bargain in email security — dual-engine antispam, dual-engine AV, attachment filtering and disclaimers — all integrated.
New features in Ninja 2.1 include disclaimer functionality, an improved antispam engine for better spam detection, and console management enhancements.
You can view the webcast I did yesterday on it here, and our company propoganda here.
