        I have multiple SMTP appenders that do not play nicely with each other.  On startup I am sending a test error as well as an email to notify of application startup.  In some cases the error email does not go out.  In other cases they both go out, however the error email also contains the ext of the startup email.  I tried fixing this by capping the buffer size.  On startup I am essentially calling a logger.error("test") as well as a logger.info("theMarkerName", "some text") very close to each other.  My SMTP appenders are defined as follows (anonymized my company's information):
