Release Notes: The ability to easily pull Header values from SMTPMessage and SMTPMessagePart has been added (duplicate header keys, such as Received, are not supported. The last header key wins.). A bug that caused an infinite loop when clients disconnected improperly has been fixed. The regex of email addresses in SMTPProcessor has been fixed. Text replacement in user-overridable SMTP messages has been fixed. The ability to shut down SimpleServer cleanly has been added.
