Pass Through and Report - The product does
not scan malformed content and lets the e-mail
message pass through unless malicious code is
found in the rest of the message. The
administrator receives an alert about the
malformed content found in the message.
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.
Action on mails with
exceeding nesting
levels Specify the action to take on inbound e-mail
messages with nesting levels exceeding the
level specified in the
Max Levels of Nested
Messages setting.
Drop - E-mail messages with exceeding nesting
levels are not delivered to the recipient(s). The
nested message is moved to the the quarantine
folder if
Quarantine Problematic Mails setting is
enabled. For more information, see
“
Quarantine ” , 151 .
Pass Through - Nested e-mail messages will be
scanned up to level specified in the Max Levels
of Nested Messages setting and then delivered
to the recipient(s).
Max mail header size Specify the maximum size (in kilobytes) of the
mail header that the product accepts. If the mail
message contains a header that exceeds the
specified value, it will be rejected. If zero (0) is
specified, the mail header size is unlimited.
Note that it is not recommended to set the max
mail header size to unlimited as this will make
the product more vulnerable to DoS attacks.
