Table 52 Option definitions
Option Definition
Use the welcome
message from the mail
server
Specifies the welcome message that appears when a host using SMTP connects
to an appliance operating in a transparent mode.
When selected, displays the welcome message of the mail server at the other
end of the connection. Prefixes extra text, if specified in the next option.
When not selected, displays the appliance's own welcome message (in the
Message processing section).
Default value is Yes.
Prepend the following
text
Specifies text for the message.
Default value is to prefix no text.
Send keepalives (NOOP
commands) during the
DATA phase
and
Keepalive interval
Prevents the connection between the appliance and the onward email server
from timing-out when the appliance is scanning large email messages by
sending a keep-alive command to the destination server. This keeps the
connection alive until the DATA phase from the sending email server to the
appliance has completed. When the data has been transferred to the appliance,
the appliance stops sending the commands and starts the DATA phase between
the appliance and the destination email server. Default value is No.
Specify how often to send the keep-alive (NOOP) commands during the DATA
phase.
Default value of interval is 55 seconds
Advanced options
Use this section to specify further settings for transparency options. You do not normally need to
change these settings.
Table 53 Option definitions
Option Definition
Allow the appliance to
generate additional
scanning alerts
Generates additional scanning alerts to warn a network administrator or other
users when specific events occur.
Default value is Yes.
The actions that the appliance takes when one of these events occurs, depends on
which detection was triggered and how the policies have been set up for each
protocol. By default, most secondary actions are not available when the appliance
is operating in a transparent mode. Only the quarantine actions are available by
default.
Allow multiple
policies per email
Allows the use of multiple policies for email messages that have more than one
recipient.
Default value is No.
If an email message has more than one recipient, you can configure the appliance
to allow different policies to apply to each of the recipients. If you do not allow
multiple policies, the appliance applies only the highest priority policy, as defined
by the order of your policies.
Add a Received
header to email
Adds Received (RCPT) commands to the email headers.
Default value is Yes.
