Class MailLogger


  • public final class MailLogger
    extends java.lang.Object
    A simplified logger used by Jakarta Mail to handle logging to a PrintStream and logging through a java.util.logging.Logger. If debug is set, messages are written to the PrintStream and prefixed by the specified prefix (which is not included in Logger messages). Messages are logged by the Logger based on the configuration of the logging system.
