OfficeScan monitors email transmitted through various email
clients.
OfficeScan checks the email’s
subject, body, and attachments for data identifiers. For a list of supported email
clients, see the
Data
Protection Lists document at:
Monitoring occurs when a user attempts to send the email. If
the email contains data identifiers, OfficeScan will
either allow or block the email.
You can define monitored and non-monitored internal email domains.
-
Monitored email domains: When
OfficeScan detects
email transmitted to a monitored domain, it checks the action for
the policy. Depending on the action, the transmission is allowed
or blocked.
 |
Note
If you select email clients as a monitored
channel, an email must match a policy for it to be monitored. In
contrast, an email sent to monitored email domains is automatically
monitored, even if it does not match a policy.
|
-
Non-monitored email domains:
OfficeScan immediately
allows the transmission of emails sent to non-monitored domains.
|
Note
Data
transmissions to non-monitored email domains and to monitored email
domains where "Monitor" is the action are similar in that the transmission
is allowed. The only difference is that for non-monitored email domains, OfficeScan does
not log the transmission, whereas for monitored email domains, the
transmission is always logged.
|
Specify domains using any of the following formats, separating
multiple domains with commas:
-
X400 format, such as /O=Trend/OU=USA, /O=Trend/OU=China
-
Email domains, such as example.com
For email messages sent through the SMTP protocol, OfficeScan checks if
the target SMTP server is on the following lists:
-
Monitored targets
-
Non-monitored targets
|
Note
|
-
Monitored email domains
-
Non-monitored email domains
This means that if an email is sent to an SMTP server on the
monitored targets list, the email is monitored. If the SMTP server
is not on the monitored targets list, OfficeScan checks
the other lists.
For emails sent through other protocols, OfficeScan only
checks the following lists:
-
Monitored email domains
-
Non-monitored email domains
