It really depends in the additional behaviour you have in mind. It is
possible to add filters to an appender. An appender can also wrap
another appender to "decorate" it with additional behavior.
Note that the cyclic buffer is an intrinsic feature of SMTPAppender. I
don't think you could transpose cyclic buffering to other appenders. You
could bu the result would not necessarily make sense.
