File Type Recognition
Select whether you want to use Intelligent File Type Recognition or not.
Trojans and other malicious code can disguise themselves with filename
extensions which are usually considered safe to use. Intelligent File Type
Recognition can recognize the real file type of the message attachment
and use that while the attachment is processed.
Advanced
Configure how to handle nested messages and specify the administrator
account to scan public folders.
Using Intelligent File Type Recognition strengthens the security, but
can degrade the system performance.
Max Levels of Nested
Messages
Specify how many levels deep to scan in nested
e-mail messages.
A nested e-mail message is a message that
includes one or more e-mail messages as
attachments. If zero (0) is specified, the
maximum nesting level is not limited.
It is not recommended to set the maximum
nesting level to unlimited as this will make the
product more vulnerable to DoS
(Denial-of-Service) attacks.
Admin User
Credentials
Specify the primary SMTP address for the
account which is used to scan items in public
folders. The user account must have
permissions to access and modify in the public
folders.
The setting is used on Microsoft Exchange 2010
platform only and affects manual, realtime, and
scheduled storage scanning. If you do not
specify any address, public folders in Exchange
Store cannot be accessed or even listed.
