Note that if this is on and there are no MIME headers contained in the message,
the appliance will continue to try and parse the message, using the protocol header
information, if available.
When this is off and MIME headers are present in the body of the message, these
MIME headers will be considered part of the preamble, and not used to parse out
the message. If the protocol headers (such as HTTP) indicate the MIME
boundaries, the appliance can parse and process individual attachments. If such
information is not available, no attachments can be parsed from the body of the
message.

Guidelines
The body of a message (that is, the payload, independent of any protocol headers)
can sometimes contain MIME headers before any preamble and before the first
MIME boundary contained in the body of the message. These MIME headers can
contain important information not available in the protocol headers, such as the
string identifying the MIME boundary. If this property is set to on, then these
MIME headers will be processed by the gateway.
If this is on and there are no MIME headers contained in the message, the
appliance will continue to try and parse the message, using the protocol header
information, if available.
