/**
 * This test checks to see if the pop3 password failure is handled correctly
 * in the case of the server dropping the connection during auth login.
 * We use POP3_RFC5034_handler so auth=login will be supported.
 * The steps are:
 *   - Have an invalid password in the password database.
 *   - Check we get a prompt asking what to do.
 *   - Check retry does what it should do.
 *   - Check cancel does what it should do.
 *   - Re-initiate connection, this time select enter new password, check that
 *     we get a new password prompt and can enter the password.
