What you can do in case your mail server doesn't throttle and protect you against DOS-attacks, is use log4j's triggering event evaluator and put throttling into that.
See: http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/net/SMTPAppender.html and: http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/spi/TriggeringEventEvaluator.html)Thus by limiting your buffer size of the SMTPAppender and make sure you can only have N triggering events per hour, you can easily avoid this problem.
Good point though, Martijn. :-) Regards, Sebastiaan Martijn Dashorst wrote:
It is a really good way to blow up your exchange server... We had a bug somewhere that generated exceptions in an endless loop. It took exchange over a whole day to empty the queue.
