Submitted for your approval: a patched version of SmtpAppender that implements the desired
functionality.  While it would still need to be thoroughly tested and vetted for fitness of
purpose, it is a good starting point for consideration by the supporting developers.

> I have a use case where some of my logged events have been marked with a custom _Marker_
(e.g. "PRIVATE").  When the _SMTP Appender_ sends out an e-mail with the triggering event
and its cyclic buffer of collected log events, I do not want the log events that have been
set with a custom _Marker_  to be included in the e-mail.
> Such a use case could be configured as follows for an _SMTP Appender_ that needs to respond
to *WARN* level or greater:
> {code:xml}...
> <Appender type="SMTP" name="smtp" bufferSize="5"
>               smtpHost="${smtpHost}" smtpPort="${smtpPort}" smtpProtocol="${smtpProtocol}"
>               smtpUsername="${smtpUsername}" smtpPassword="${smtpPassword}"
>               subject="${smtpSubject}"
>               from="${smtpFrom}"
>               to="${smtpTo}"
>               replyTo="${smtpReplyTo}"
>               cc="${smtpCc}"
>               bcc="${smtpBcc}"
>        >
>       <Layout type="PatternLayout">
>         <Pattern>%m</Pattern>
>       </Layout>
>       <Filters>
>         <MarkerFilter marker="PRIVATE" onMatch="DENY" onMismatch="NEUTRAL"/>
>         <ThresholdFilter level="warn" onMatch="ACCEPT" onMismatch="DENY"/>
>       </Filters>
>     </Appender>
> ...
> {code}
> Here is a patch that I made to _org.apache.logging.log4j.core.appender.SmtpAppender.java_
that seems to support this use case:
