I was once debugging a deployment issue where one server wouldn't send outgoing email, even though it was running the same version of our application software as other machines that were functioning just fine. After a while I traced it down to the fact that four years ago a developer had stuck an extra mail JAR file into the Tomcat
lib/ directory. This incident showed me that every server performing a function should be exactly the same as every other server performing that function.
