3.1.4 Message quarantine
The Message quarantine is a special mailbox defined by the system administrator to store potentially infected
messages and SPAM. Messages stored in quarantine can be analyzed or cleaned later using a newer virus signature
database.
There are two types of message quarantine systems that can be used.
One option is to use the Microsoft Exchange quarantine system (this applies only to Microsoft Exchange Server
2007/2010). In this case, the Exchange's internal mechanism is used to store potentially infected messages and
SPAM. Additionally, you can add a separate quarantine mailbox (or number of mailboxes) for specific recipients if
needed. This means that potentially infected messages, which were originally sent to a specific recipient, will be
delivered to separate quarantine mailbox instead of being delivered to Exchange's internal quarantine mailbox. This
might be useful in some cases to keep potentially infected messages and SPAM more organized.
Other option is to use Common message quarantine. If you are using an earlier version of Microsoft Exchange
Server (5.5, 2000 or 2003), then you simply specify Common message quarantine, which is a mailbox that will be
used to store potentially infected messages. In this case, Exchange's internal quarantine system is not used.
Instead, a mailbox specified by the system administrator is used for this purpose. As with the first option, you can
add a separate quarantine mailbox (or number of mailboxes) for specific recipients. The result is that potentially
infected messages are delivered to a separate mailbox instead of being delivered to common message quarantine.
Common message quarantine - you can specify common message quarantine address here (e.g.
[e-mail]), or you can use the Microsoft Exchange Server 2007/2010 internal quarantine
system instead by leaving this field blank and choosing Quarantine message to the mail server system
quarantine (provided that the Exchange quarantine exists in your environment) from the drop-down menu at
the bottom. Emails are then delivered to quarantine by Exchange's internal mechanism using its own settings.
NOTE: By default, this internal quarantine is not activated within Exchange. If you want to activate it, you need
to open Exchange Management Shell and type in following command:
Set-ContentFilterConfig -QuarantineMailbox [e-mail]
(replace [e-mail] by the actual mailbox you want Microsoft Exchange to use as an internal quarantine
mailbox, e.g. [e-mail])
