If the number of mailboxes in your active directory exceeds your license count a message will be entered into your
Microsoft Exchange Server log reading, "Protection status changed due to exceeded number of mailboxes (count)
covered by your license (count)." Your ESET Mail Security will also notify you by changing its
Protection status
to
ORANGE
and displaying a message informing you that you have 42 days left before your protection will be disabled. If
you receive this notification, please contact your sales representative to purchase additional licenses.
If the 42 days period has passed and you did not add the required licenses to cover the exceeding mailboxes, your
Protection status
will change to
RED
. The message will inform you that your protection has been disabled. If you
receive this notification, immediately contact your sales representative to purchase additional licenses.
2.6 Post-Installation Configuration
There are several options that have to be configured after the product installation.
Antispam protection setup
This section describes the settings, methods and techniques you can use to protect your network from spam. We
recommend reading the following instructions carefully before choosing the most suitable combination of settings for
your network.
Spam management
To ensure a high level of Antispam protection you must set actions to be performed on messages already marked as
SPAM.
There are three options available:
1. Deleting spam
The criteria for a message to be marked as SPAM by ESET Mail Security are set reasonably high, decreasing the
chances of deleting legitimate email. The more specific the Antispam settings, the less likely it is to delete legitimate
email. Advantages of this method include very low consumption of system resources and less administration. The
drawback to this method is that if a legitimate email is deleted it cannot be restored locally.
2. Quarantine
This option excludes the risk of deleting legitimate email. Messages can be restored and resent to the original
recipients immediately. The drawbacks of this method are higher consumption of system resources and additional
time required for email quarantine maintenance. You can use two methods to quarantine email:
A. Internal Exchange Server quarantine:
- If you want to use the internal server quarantine make sure the
Common message quarantine
field on the
right pane in the advanced settings menu (under
Mail server protection > Message quarantine
) is left blank.
Also make sure that the
Quarantine message to the mail server system quarantine
option is selected from
the drop-down menu at the bottom.
B. Custom quarantine mailbox:
- If you type the desired mailbox in the
Common message quarantine
field ESET Mail Security will move all
new spam messages into your custom mailbox.
3. Forwarding spam
Spam will be forwarded along to its recipient. However, ESET Mail Security will fill in the relevant MIME header with
the SCL value into each message. Based on the SCL value the relevant action will be executed by the Exchange
server IMF (Intelligent Message Filtering).

Antispam Engine
The Antispam engine offers the three following configurations -
Recommended, Most accurate, Fastest
.
If there is no need to optimize your configuration to allow maximum throughput (e.g. high server load), we
recommend you select the
Most accurate
option. When the
Recommended
configuration is set, the server will
automatically adjust its settings based on scanned messages to balance the load. When
Most accurate
is enabled, the
