Spring boot integration mail - authorization failed error

Question

Following is my spring configuration bean for pop3 connection,

    @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();
    }

Also double checked the credentials that looks good. Getting the below exception,

2018-06-22 19:27:54.351 ERROR 2092 --- [ask-scheduler-2] o.s.integration.handler.LoggingHandler : org.springframework.messaging.MessagingException: failure occurred while polling for mail; nested exception is javax.mail.AuthenticationFailedException: authorization failed at org.springframework.integration.mail.MailReceivingMessageSource.receive(MailReceivingMessageSource.java:131) at org.springframework.integration.endpoint.SourcePollingChannelAdapter.receiveMessage(SourcePollingChannelAdapter.java:224) at org.springframework.integration.endpoint.AbstractPollingEndpoint.doPoll(AbstractPollingEndpoint.java:245) at org.springframework.integration.endpoint.AbstractPollingEndpoint.access$000(AbstractPollingEndpoint.java:58) at org.springframework.integration.endpoint.AbstractPollingEndpoint$1.call(AbstractPollingEndpoint.java:190) at org.springframework.integration.endpoint.AbstractPollingEndpoint$1.call(AbstractPollingEndpoint.java:186) at org.springframework.integration.endpoint.AbstractPollingEndpoint$Poller$1.run(AbstractPollingEndpoint.java:353) at org.springframework.integration.util.ErrorHandlingTaskExecutor$1.run(ErrorHandlingTaskExecutor.java:55) at org.springframework.core.task.SyncTaskExecutor.execute(SyncTaskExecutor.java:50) at org.springframework.integration.util.ErrorHandlingTaskExecutor.execute(ErrorHandlingTaskExecutor.java:51) at org.springframework.integration.endpoint.AbstractPollingEndpoint$Poller.run(AbstractPollingEndpoint.java:344) at org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run(DelegatingErrorHandlingRunnable.java:54) at org.springframework.scheduling.concurrent.ReschedulingRunnable.run(ReschedulingRunnable.java:81) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(Unknown Source) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: javax.mail.AuthenticationFailedException: authorization failed at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:208) at javax.mail.Service.connect(Service.java:295) at javax.mail.Service.connect(Service.java:176) at javax.mail.Service.connect(Service.java:125) at org.springframework.integration.mail.AbstractMailReceiver.connectStoreIfNecessary(AbstractMailReceiver.java:286) at org.springframework.integration.mail.AbstractMailReceiver.openFolder(AbstractMailReceiver.java:293) at org.springframework.integration.mail.AbstractMailReceiver.receive(AbstractMailReceiver.java:319) at org.springframework.integration.mail.MailReceivingMessageSource.receive(MailReceivingMessageSource.java:112) ... 19 more

There is an option like this:

/**
 * The Java Mail properties.
 * @param javaMailProperties the javaMailProperties.
 * @return the spec.
 * @see AbstractMailReceiver#setJavaMailProperties(Properties)
 */
public S javaMailProperties(Properties javaMailProperties) {

You can specify there mail.debug = true to trace what's going on with mail protocol during interaction.

UPDATE

We have this in your logs:

DEBUG POP3: connecting to host "172.16.1.45", port 995, isSSL false
19:54:46.746 [task-scheduler-1] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Returning cached instance of singleton bean 'errorChannel'
19:54:46.753 [task-scheduler-1] DEBUG org.springframework.integration.channel.PublishSubscribeChannel - preSend on channel 'errorChannel', message: ErrorMessage [payload=org.springframework.messaging.MessagingException: failure occurred while polling for mail; nested exception is javax.mail.MessagingException: Connect failed;
  nested exception is:
    java.net.ConnectException: Connection refused: connect, headers={id=290f4c5a-2dfe-d7cb-0637-a0e9f0394daa, timestamp=1529677486753}]

So, it can't just connect to the 172.16.1.45:995. There is no authentication handshake yet.

See an UPDATE in my answer. – Artem Bilan Jun 22 '18 at 14:32
Can I replace **pop.gmail.com** instead of **172.16.1.45:995** I can't get a clue for this, Does it happen due to any proxy or firewall – Sharan De Silva Jun 22 '18 at 14:38
Right, you can do that. According your logs the URL must be like `pop3://sharanraj.siluvaipillai:*****@pop.gmail.com/INBOX`. However for GMail you should consider to you `application token` instead of your original password: https://developers.google.com/gmail/api/auth/about-auth – Artem Bilan Jun 22 '18 at 14:43
If you can't even connect you're probably running into a [proxy or firewall issue](https://javaee.github.io/javamail/FAQ#condebug). The JavaMail FAQ describes how to [connect through a proxy server](https://javaee.github.io/javamail/FAQ#proxy). – Bill Shannon Jun 22 '18 at 19:32
