27  * The POP3* tests all presume the existence of the following parameters:
28  * mailserver: localhost (running on the default port 110)
29  * account: username=test; password=password
30  * account: username=alwaysempty; password=password.
31  * mail: At least four emails in the test account and zero emails
32  * in the alwaysempty account
33  *
34  * If this won't work for you, you can change these parameters in the
35  * TestSetupParameters class.
36  *
37  * The tests were originally run on a default installation of James.
38  * Your mileage may vary based on the POP3 server you run the tests against.
39  * Some servers are more standards-compliant than others.
