6.5.8. SMTP Log Receiver for IDP
Events
Example 6.20. Configuring an SMTP Log Receiver
In this example, an IDP Rule is configured with an SMTP Log Receiver. Once an IDP event occurs, the Rule is
triggered. At least one new event occurs within the Hold Time of 120 seconds, thus reaching the log threshold
level (at least 2 events have occurred). This results in an email being sent containing a summary of the IDP
events. Several more IDP events may occur after this, but to prevent flooding the mail server, NetDefendOS will
wait 600 seconds (equivalent to 10 minutes) before sending a new email. An SMTP server is assumed to have
been configured in the address book with the name smtp-server.
