Spring启动集成邮件 - 授权失败错误

以下是我用于pop3连接的spring配置bean，

@Bean
    public IntegrationFlow mailListener() {
        return IntegrationFlows.from(Mail.pop3InboundAdapter("pop3://sample.test:Sample2test_1@xxx.xx.x.xx/INBOX")
                 .shouldDeleteMessages(true).get(), 
                 e -> e.poller(Pollers.fixedRate(5000).maxMessagesPerPoll(1)))
            .<Message>handle((payload, header) -> logMail(payload))
            .get();
    }

还要仔细检查看起来不错的凭据 . 获得以下异常，
