$Id: POP3ClientCommandsTest.java 165675 2005-05-02 20:09:55Z rwinston $ The POP3* tests all presume the existence of the following parameters: mailserver: localhost (running on the default port 110) account: username=test; password=password account: username=alwaysempty; password=password. mail: At least four emails in the test account and zero emails in the alwaysempty account If this won't work for you, you can change these parameters in the TestSetupParameters class. The tests were originally run on a default installation of James. Your mileage may vary based on the POP3 server you run the tests against. Some servers are more standards-compliant than others.
