See org.apache.log4j.net.SMTPAppender.

StringWriter, then retrieve the data from that writer later on. You'd
probably want some kind of reset mechanism, too.

Read the source and javadoc? Seriously, it's how I learned a bit more
about what goes on under the covers.

Ceki is currently writing a fuller manual, I believe.
