David, You could loop through all the Appenders, looking for the one with your specific name, and then change the appropriate property at runtime.
I found really useful code for looping through & finding Appenders from Andrew Andrew Elmhorst and Nicko Cadell, posted here: http://www.l4ndash.com/Log4NetMailArchive%2Ftabid%2F70%2Fforumid%2F1%2Fpostid%2F15439%2Fview%2Ftopic%2FDefault.aspx I had to tweak it a bit more for BufferingForwarding Appenders - but if your Appenders are hung off the root and are just rollingfile Appenders or something else with no indirection, you can probably use the simplest sample code.
