Configuring Attachment Checking
Introduction to Attachment Checking
This chapter explains how to set up Attachment Checking in GFI
MailSecurity. The Attachment Checking 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 Checking
rule allows you to block attachments of a certain type.

In GFI MailSecurity, you can configure attachment rules from the
Attachment Checking 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).
Creating an Attachment Checking rule
To create an Attachment Checking rule:
1. Click the GFI MailSecurity  Attachment Checking node.
2. From the Attachment Checking page (in the right window), click
Add Rule.
