Mail Alerting - D-Link NetDefendOS User Manual

2.3.6. Mail Alerting

Overview
By creating a Mail Altering object, NetDefendOS can be configured to send log messages in an
email to a specified email address via a nominated external SMTP server. The Mail Altering object
can be considered to be like other types of log receivers and it is possible to select the type of log
messages that are sent.
The intended purpose of this feature is to provide a means of quickly altering the administrator
of any important NetDefendOS events so the selected level of severity for the events sent in this
way will usually be very high.
Mail Altering Object Properties
Many Mail Alerting object properties are the same as in other types of log receiver object and will
not be listed again in this section. The object properties that are unique are the following:
• SMTP Server
The IP address of an SMTP server that will forward generated emails to the destination email
address. This can also be an FQDN address object or a DNS resolvable FQDN (note that both
require that a DNS server is configured in NetDefendOS).
• Server Port
The port number that the SMTP server listens on. This is set by default to the standard port
number of 25.
• SMTP Recipient
A single destination email address for outgoing mails.
• SMTP Sender
A string which will be the sender name text in emails.
• Subject
A string which will be the subject text in emails.
• Send Test Email
This is not a property but a button in the Web Interface used to test the SMTP properties
entered. It has a CLI equivalent and is explained further later in this section.
Event Trigger Mode
• Single event trigger
A single email is sent for at least each eligible event. The Event count threshold and Event
count period values are not used with this option. However, when a single event is ready for
sending it must wait for the Keep collecting before sending period so other eligible events can
be added to the mail.
• Rate of events trigger
