The SmtpAppender type exposes the following members.

	Name	Description
	SmtpAppender	Default constructor

	Name	Description
	Authentication	The mode to use to authentication with the SMTP server
	Bcc	Gets or sets a semicolon-delimited list of recipient e-mail addresses that will be blind carbon copied.

	BufferSize	Gets or sets the size of the cyclic buffer used to hold the logging events. (Inherited from BufferingAppenderSkeleton.)
	Cc	Gets or sets a comma- or semicolon-delimited list of recipient e-mail addresses that will be carbon copied (use semicolon on .NET 1.1 and comma for later versions).
	EnableSsl	Enable or disable use of SSL when sending e-mail message
	ErrorHandler	Gets or sets the IErrorHandler for this appender. (Inherited from AppenderSkeleton.)
	Evaluator	Gets or sets the ITriggeringEventEvaluator that causes the buffer to be sent immediately. (Inherited from BufferingAppenderSkeleton.)
	FilterHead	The filter chain. (Inherited from AppenderSkeleton.)
	Fix	Gets or sets a the fields that will be fixed in the event (Inherited from BufferingAppenderSkeleton.)
	From	Gets or sets the e-mail address of the sender.
	Layout	Gets or sets the ILayout for this appender. (Inherited from AppenderSkeleton.)
	LocationInfo	Obsolete. Obsolete
	Lossy	Gets or sets a value that indicates whether the appender is lossy. (Inherited from BufferingAppenderSkeleton.)
	LossyEvaluator	Gets or sets the value of the ITriggeringEventEvaluator to use. (Inherited from BufferingAppenderSkeleton.)
	Name	Gets or sets the name of this appender. (Inherited from AppenderSkeleton.)
	OnlyFixPartialEventData	Obsolete. Gets or sets a value indicating if only part of the logging event data should be fixed. (Inherited from BufferingAppenderSkeleton.)
	Password	The password to use to authenticate with the SMTP server
	Port	The port on which the SMTP server is listening
	Priority	Gets or sets the priority of the e-mail message
	ReplyTo	Gets or sets the reply-to e-mail address.
	RequiresLayout	This appender requires a log4net.Layout to be set. (Overrides AppenderSkeletonRequiresLayout.)
	SmtpHost	Gets or sets the name of the SMTP relay mail server to use to send the e-mail messages.
	Subject	Gets or sets the subject line of the e-mail message.
	SubjectEncoding	Gets or sets the subject encoding to be used.

	To	Gets or sets a comma- or semicolon-delimited list of recipient e-mail addresses (use semicolon on .NET 1.1 and comma for later versions).
	Username	The username to use to authenticate with the SMTP server

	Name	Description
	ActivateOptions	Initialize the appender based on the options set (Inherited from BufferingAppenderSkeleton.)
	AddFilter	Adds a filter to the end of the filter chain. (Inherited from AppenderSkeleton.)
	Append(LoggingEvent)	Append a bulk array of logging events. (Inherited from AppenderSkeleton.)
	Append(LoggingEvent)	This method is called by the DoAppend(LoggingEvent) method. (Inherited from BufferingAppenderSkeleton.)
	ClearFilters	Clears the filter list for this appender. (Inherited from AppenderSkeleton.)
	Close	Closes the appender and release resources. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent)] method. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent[])] method. (Inherited from AppenderSkeleton.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	FilterEvent	Test if the logging event should we output by this appender (Inherited from AppenderSkeleton.)
	Finalize	Finalizes this appender by calling the implementation's Close method. (Inherited from AppenderSkeleton.)
	Flush	Flush the currently buffered events (Inherited from BufferingAppenderSkeleton.)
	Flush(Boolean)	Flush the currently buffered events (Inherited from BufferingAppenderSkeleton.)
	Flush(Int32)	Flushes any buffered log data. (Inherited from BufferingAppenderSkeleton.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsAsSevereAsThreshold	Checks if the message level is below this appender's threshold. (Inherited from AppenderSkeleton.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnClose	Close this appender instance. (Inherited from BufferingAppenderSkeleton.)
	PreAppendCheck	Called before [M:Append(LoggingEvent)] as a precondition. (Inherited from AppenderSkeleton.)
	RenderLoggingEvent(LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	RenderLoggingEvent(TextWriter, LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	SendBuffer	Sends the contents of the cyclic buffer as an e-mail message. (Overrides BufferingAppenderSkeletonSendBuffer(LoggingEvent).)
	SendEmail	Send the email message
	SendFromBuffer	Sends the contents of the buffer. (Inherited from BufferingAppenderSkeleton.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

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.

Caution

Authentication and setting the server Port are only available on the MS .NET 1.1 runtime. For these features to be enabled you need to ensure that you are using a version of the log4net assembly that is built against the MS .NET 1.1 framework and that you are running the your application on the MS .NET 1.1 runtime. On all other platforms only sending unauthenticated messages to a server listening on port 25 (the default) is supported.

Authentication is supported by setting the Authentication property to either Basic or Ntlm. If using Basic authentication then the Username and Password properties must also be set.

To set the SMTP server port use the Port property. The default port is 25.
