When you create an SMTP appender, the logger sends log events as an email. You can specify multiple email addresses that you want to receive the email. For example, you can use the SMTP appender to send an email when an error or fatal error occurs.

Before you use the SMTP appender, you must put the mail.jar file into the

<Dynamic Data Masking installation>/lib/ext

directory. On Windows, you must remove and restart the Dynamic Data Masking Server to update the Server configuration in the Windows Registry. On Unix, you must restart the Dynamic Data Masking Server.
