MailFender for Exchange Server protects your Exchange 2000/2003 Server from spam and virus-infected messages. It also provides you with a powerful rule set for defining your e-mail policy within your organization.
The rule set provided by MailFender lets you add legal and commercial disclaimers, remove attachments from messages, detect messages containing inappropriate language, detect and clean viruses, quarantine or reject spam. It works with Exchange Server 2000, Exchange Server 2003, and the standard SMTP server, supplied with all Windows Server operating systems from Windows 2000 Server onwards. The virus engine is optionally powered by either Sophos or Kaspersky.
