@Plugin(name="SMTP",

        elementType="appender",
        printObject=true)
public final class SmtpAppender
extends AbstractAppender

Send an e-mail when a specific logging event occurs, typically on errors or fatal errors.

The number of logging events delivered in this e-mail depend on the value of BufferSize option. The SmtpAppender keeps only the last BufferSize logging events in its cyclic buffer. This keeps memory requirements at a reasonable level while still delivering useful application context. By default, an email message will formatted as HTML. This can be modified by setting a layout for the appender. By default, an email message will be sent when an ERROR or higher severity message is appended. This can be modified by setting a filter for the appender.
