Types of Outbound Email Filtering
You can add outbound filtering to each package, helping to ensure the safety and
appropriateness of information being sent from your corporate email system to valued
customers or business partners.
Filter Type
Description
Content
Filtering
This feature automatically prevents inappropriate, malicious, or
confidential content from leaving your corporate email system,
allowing you to monitor and enforce your corporate email
policies.
Attachment
Filtering
Outbound attachments can be filtered by size, by MIME content
type, or by binary content, according to your corporate email
policies.
Virus
Scanning
Outbound virus scanning stops viruses and worms from leaving
your corporate email system, preventing your enterprise from
being the source of email-borne viruses to customers, suppliers,
and partners.
Configurable Actions for Filtered Email
In Email Protection, email filtering policies control how emails are filtered within a
specific Domain and how Email Protection will respond during email filtering and
reporting. Depending on the feature package that is licensed for a domain, specific email
filters will be available to be enabled and configured. Also, depending on the enabled
email filter, various actions must be configured that define how Email Protection will
respond if an email violates the specific filter policy.
User-level Deny Lists
and Allow Lists
Maintained by you and/or the user, Deny lists indicate sender
addresses from which email is denied automatically. Allow lists
indicate sender addresses from which email is allowed without
spam filtering (all other enabled filtering will be applied).
You can designate a single email address, entire domains or IPs, or
use wildcards to designate ranges of addresses. Optionally, you
can save these lists to a spreadsheet file.
These lists affect only the emails received for the designated user
account and its alias addresses (
user-level
lists).
Recipient Shield List
You can define a list of recipient email addresses for which you
want to specify special email actions (for example, you want to
deny all emails for a user who is an ex-employee). You can also
specify the email action to take if the recipient email address is
invalid in your system (permfailed by your email server as an
invalid recipient
).
