Hi @gzigldrum, thanks for replying. The below message is what i see in logs. As, per the below error "Couldn't connect to host, port: localhost, 25; timeout 30000;"  - As I highlighted in red color, why it is trying to connect to localhost? I provided the SMTP hostname:port no. in the "Alerts: Mail Server Hostname" config. I did not get any solid info from the log about why the error is occurring. Do you find anything from the below message?    Stacktrace --------------------------------------------------------------------------------------------------------------------------------------- com.sun.mail.util.MailConnectException: Couldn't connect to host, port: localhost, 25; timeout 30000; nested exception is: java.net.ConnectException: Connection refused (Connection refused) at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2100) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:699) at javax.mail.Service.connect(Service.java:366) at org.apache.camel.component.mail.DefaultJavaMailSender.send(DefaultJavaMailSender.java:112) at org.apache.camel.component.mail.MailProducer.process(MailProducer.java:63) at org.apache.camel.util.AsyncProcessorConverterHelper$ProcessorToAsyncProcessorBridge.process(AsyncProcessorConverterHelper.java:61) at org.apache.camel.processor.SendProcessor$2.doInAsyncProducer(SendProcessor.java:173) at org.apache.camel.impl.ProducerCache.doInAsyncProducer(ProducerCache.java:436) at org.apache.camel.processor.SendProcessor.process(SendProcessor.java:168) at org.apache.camel.processor.RedeliveryErrorHandler.process(RedeliveryErrorHandler.java:541) at org.apache.camel.processor.CamelInternalProcessor.process(CamelInternalProcessor.java:198) at org.apache.camel.processor.Pipeline.process(Pipeline.java:120) at org.apache.camel.processor.Pipeline.process(Pipeline.java:83) at org.apache.camel.processor.CamelInternalProcessor.process(CamelInternalProcessor.java:198) at org.apache.camel.processor.CamelInternalProcessor.process(CamelInternalProcessor.java:198) at org.apache.camel.util.AsyncProcessorHelper.process(AsyncProcessorHelper.java:109) at org.apache.camel.processor.MulticastProcessor.doProcessParallel(MulticastProcessor.java:841) at org.apache.camel.processor.MulticastProcessor.access$200(MulticastProcessor.java:85) at org.apache.camel.processor.MulticastProcessor$1.call(MulticastProcessor.java:328) at org.apache.camel.processor.MulticastProcessor$1.call(MulticastProcessor.java:314) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.net.ConnectException: Connection refused (Connection refused) at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:606) at com.sun.mail.util.SocketFetcher.createSocket(SocketFetcher.java:329) at com.sun.mail.util.SocketFetcher.getSocket(SocketFetcher.java:238) at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2066) ...
