Cool. I knew it wasn't personal, and the SMTPAppender wasn't the point.
(I'll send the patch under a seperate header.) I just wanted to make sure
that everyone writing code for the project remembers how important it is to
make the code extensible via subclassing. (By not using package
members/methods, providing accessor methods, using accessors within the code
instead of referencing the member directly [which also tends to make faster
code since it can then get the variable from the stack instead of the heap],
etc.) Especially on a project like this that's used by thousands of
programmers, the ease with which they can extend -- rather than rewrite --
that functionality is extremely important.
That said, of course, log4j is extremely flexible and well written. It's
just that, being so, problems like the above are all the more glaring.

Hello Jim,
If you feel that your contribution is being ignored then nag. If that
doesn't work, then nag some more. I would dare say that participants in the
log4j project are mere mortals. That applies to other open source projects
in Jakarta, XML, PHP and httpd. We make mistakes, overlook excellent
contributions, write buggy code, under document etc etc.
However, it is never personal. You are kindly requested to resubmit your
SMTPAppender patch. I apologize for the inconvenience. Regards, Ceki
