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.
Security Options
Configure security options to limit actions of malformed and problematic
messages.
Using Intelligent File Type Recognition strengthens the security but
can degrade the system performance.
Action on Malformed
Mails Specify the action for non-RFC compliant
e-mails. If the message has an incorrect
structure, the product cannot parse the message
reliably.
Drop the Whole Message - Do not deliver the
message to the recipient.
Pass Through - The product allows the message
to pass through.
Pass Through and Report - The product allows
the message to pass through, but sends a report
to the administrator.
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.
