4 Select Only Un-Scanned Items to enable background scanning only to those messages
that have not been scanned yet.
5 Select Force Scan All to scan items irrespective of whether the item has a scan stamp
or not.
If an item has a scan stamp, it means that the item is scanned and up to date.
6 Select
Update Scan Stamp to perform background scanning up to date.
When you deselect this option, do not update stamp. This feature is useful e.g. if
the vendor wants to access the messages but not necessarily virus scan them.
7 Choose the
From Date and To Date fields to schedule the scan stamp update.
You also have an option to select
Till Date if required.
8 In
Transport Scan Settings:
Select Enable to enable transport scanning. If deselected, the remaining options
also becomes inactive.
Transport Scan Stamp - select to benefit direction-based SMTP scanning control.
Scan Inbound Mails - select to scan messages coming from an external server (for
example, Internet-based email messages). If this option is selected and the next
two options are deselected, then a mail going to a different domain is not
scanned.
Scan Outbound Mails - select to scan any email message that leaves your Exchange
Server or Exchange organization.
Messages are designated as outbound if at least one recipient has an external
address.
Scan Internal Mails - select to scan email messages that are being routed from one
location inside your domain to another location inside your domain.
Messages are designated as Internal if they originate from inside your domain
and ALL the recipients are located inside your domain.
9 Click
Apply.
Note
Under Microsoft Virus Scanning API (VSAPI), enter the Lower Age Limit (seconds) to
specify whether to scan all emails or only those that are not older than the date/time
mentioned in the setting.
This is useful in a scenario where the customer suspects an outbreak/infection of emails
that came only in the last 2 days.
This will also help in finishing the background scanning faster and hence result in lesser
load on the server.
