5 Implementing Your Email Content Security Policy
MailMarshal provides a powerful and flexible framework that allows you to enforce an Email Content Security policy. Configure MailMarshal to support your organizational Acceptable Use Policy for email usage.
An Email Content Security policy typically has several goals:
•To block virus or malware infected email.
•To prevent illegitimate relaying of email.
•To control who can send email through your server.
•To prevent malicious email attacks
•To filter email messages and attachments according to local policies of the organization.
MailMarshal includes facilities to perform these tasks. MailMarshal is configured by default with settings and rules that implement some best practices and common filtering policies out of the box. This chapter gives an overview of typical policies and policy-related tasks, and the MailMarshal elements available to accomplish each task.
