Configuring Content & Attachment
Introduction to content checking
This chapter explains how to set up content & attachment checking in
GFI MailSecurity. The content checking feature allows you to setup a
policy regarding what types of email 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, for example, blocking all executable
Other examples of rules are:
blocking all mails which contain certain words
blocking all mails with attachments that can contain programs or
scripts. (*.vbs) (Love Letter!)
blocking certain users sending attachments all together.
Types of Content checking rules
There are two types of content checking rules:
Content checking rule
this rule allows you to search a mail
message and its attachments for certain words. This allows you to
block mails and attachments with certain content. For example, you
can block attachments with specific words.
Attachment checking rule
An attachment checking rule allows you
to block attachments of a certain type.
Both rules can be applied to all users or a specified list of users.

1. Highlight the content checking node in the GFI MailSecurity
