Hi Team, I have created a BPMN with mail service, If the task reaches the due date it will trigger automatic mails based on pattern given in Time cycle in boundary event and I used the below configuration for mail server, am getting the mail as I expected but the issue is occasionally am getting the below error seems the flowable engine is taking default mail configuration, But the issue is occurring randomly. _ **BPMN** _ ![Reminder](https://canada1.discourse-cdn.com/flex035/uploads/flowable/original/2X/f/f9740d5229e55ed4109871db22eee9beaf29fb4e.png) _ **Configuration :** _ ```auto flowable.mail.server.default-from=xxx@yyy.com flowable.mail.server.host=xxx.yyy.com flowable.mail.server.port=25 flowable.mail.server.username=xxx flowable.mail.server.password=yyy ``` _ **Error** _ ```auto org.flowable.common.engine.api.FlowableException: Could not send e-mail in execution be12fd84-c8b3-11ed-b122-0a18177a00ea at org.flowable.engine.impl.bpmn.behavior.MailActivityBehavior.handleException(MailActivityBehavior.java:497) at org.flowable.engine.impl.bpmn.behavior.MailActivityBehavior.execute(MailActivityBehavior.java:130) at org.flowable.engine.impl.agenda.ContinueProcessOperation.executeActivityBehavior(ContinueProcessOperation.java:286) at org.flowable.engine.impl.agenda.ContinueProcessOperation.executeSynchronous(ContinueProcessOperation.java:168) at org.flowable.engine.impl.agenda.ContinueProcessOperation.continueThroughFlowNode(ContinueProcessOperation.java:123) at org.flowable.engine.impl.agenda.ContinueProcessOperation.run(ContinueProcessOperation.java:86) at org.flowable.common.engine.impl.AbstractEngineConfiguration.lambda$new$0(AbstractEngineConfiguration.java:195) at org.flowable.engine.impl.interceptor.CommandInvoker.executeOperation(CommandInvoker.java:130) at org.flowable.engine.impl.interceptor.CommandInvoker.executeOperations(CommandInvoker.java:114) at org.flowable.engine.impl.interceptor.CommandInvoker.execute(CommandInvoker.java:72) at org.flowable.engine.impl.interceptor.BpmnOverrideContextInterceptor.execute(BpmnOverrideContextInterceptor.java:26) at org.flowable.common.engine.impl.interceptor.TransactionContextInterceptor.execute(TransactionContextInterceptor.java:53) at org.flowable.common.engine.impl.interceptor.CommandContextInterceptor.execute(CommandContextInterceptor.java:98) at org.flowable.common.spring.SpringTransactionInterceptor.lambda$execute$0(SpringTransactionInterceptor.java:57) at org.springframework.transaction.support.TransactionTemplate.execute(TransactionTemplate.java:140) at org.flowable.common.spring.SpringTransactionInterceptor.execute(SpringTransactionInterceptor.java:57) at org.flowable.common.engine.impl.interceptor.LogInterceptor.execute(LogInterceptor.java:30) at org.flowable.common.engine.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:56) at org.flowable.common.engine.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:51) at org.flowable.job.service.impl.asyncexecutor.ExecuteAsyncRunnable.executeJob(ExecuteAsyncRunnable.java:127) at org.flowable.job.service.impl.asyncexecutor.ExecuteAsyncRunnable.run(ExecuteAsyncRunnable.java:115) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.commons.mail.EmailException: Sending the email to the following server failed : localhost:1025 at org.apache.commons.mail.Email.sendMimeMessage(Email.java:1469) at org.apache.commons.mail.Email.send(Email.java:1496) at org.flowable.engine.impl.bpmn.behavior.MailActivityBehavior.execute(MailActivityBehavior.java:125) ... 22 common frames omitted Caused by: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: localhost, 1025;

Kindly suggest me to overcome this issue. `flowable.version - 6.7.0` ---

Are you running in a cluster configuration? This behavior would suggest one of the nodes is missing the mail configuration, perhaps not running the production profile or something similar. ---

Hi @gdharley , We are running flowable engine in two instances both the instance were pointing same DB and both the instances have the mail configuration, But I don’t know why this issue is occurring occasionally. Is there any way to debug this ? Thanks for the reply. ---

Debugging this will be very difficult as it happens so infrequently, however you can mitigate the issue by setting the email task to be asynchronous. That way, if it does fail, it will be automatically retried up to 3 times. ---

Hi @gdharley , As you mentioned in previous reply the configuration is missing in one of the Environment ( _we are using Jenkins to build it is taking configuration from some other location not from the source code so we missed_ ) , After we fixed that, It is working as expected. Thanks !
