5	Configuring Attachment Filtering

5.1	Introduction to Attachment Filtering

This chapter explains how to set up Attachment Filtering in GFI MailSecurity. The Attachment Filtering feature allows you to set up a policy regarding what types of email attachments you will allow on your mail server. To set up such a policy, GFI MailSecurity uses the concept of 'Rules'. A rule is a condition that you set, such as, “block all executable attachments”. This means that an Attachment Filtering rule allows you to block attachments of a certain type.

In GFI MailSecurity, you can configure attachment rules from the Attachment Filtering node. This page contains the options that enable you to create, delete, enable or disable rules. In addition, it lists all the existing attachment rules, including their status and the order in which these rules are applied to emails (i.e. priority).
