> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.2
> Reporter: Natalia Britvikhina
> Priority: Major
> Fix For: 2.9.0

>
> SmtpAppender has a bufferSize parameter that allows for buffering of events
> for inclusion in the message. I have a use case where I don't want to include
> any previous events but just the Error event that triggered the email.
> Unfortunately setting bufferSize to 0 cause a +"The maxSize argument (0) is
> not a positive integer"+ Exception from CyclicBuffer.
> Looking at the SmtpManager code it appears to be possible to allow for the
> buffer to be null if bufferSize is set to 0, and only send the message with
> the current event.
