Issues with Configuring Email Server

... server. we found no issue with connectivity.
->ping SMTP_HOST
->telnet SMTP_HOST:PORT

while sending mails we are getting an error.

Any suggestion to resolve this.

Thanks.

Hi, can you please attach the application server log? Thanks.

Hi Eliot, thanks for quick reply.

PFA log file.

server.log

In your log I see that there is an SSL handshake exception. You may find this forum post useful: forum.appian.com/.../e-116808

We still getting the error:

06:59:07,128 ERROR [org.jboss.as.ejb3.invocation] (Appian Work Item - 3 - NotificationsEmail) JBAS014134: EJB Invocation failed on component UnattendedRequestHandlerBean for method public abstract com.appiancorp.process.engine.ContinuationResponse com.appiancorp.ra.workpoller.UnattendedRequestListener.onMessage(com.appiancorp.process.engine.UnattendedRequest): javax.ejb.EJBException: com.appiancorp.process.engine.EmailBodyException: Email body failed to render

It looks like that is actually a different error. Please confirm that you are using the correct credentials to access the email account, that you are using a port that is available, and that you are still able to connect via telnet. Also please double-check that you have correctly configured the custom.properties file. From the information you have provided, it appears that you may not have configured the "Rendering Email Body" section of the properties. After verifying these things, if the problem persists, please attach your custom.properties file and your application-server.log file (found in your <APPIAN_HOME>/logs folder) so that I can review them further.

The application server makes a GET request via conf.suite.MAIL_SCHEME://conf.suite.MAIL_SERVER_AND_PORT to retrieve the JSP that will be used as a template to render the body of the email. This step is called "Rendering the email body". If these settings are not defined the URL defaults to
conf.suite.SCHEME://conf.suite.SERVER_AND_PORT.

In this particular case, as Eliot mentioned, there's an SSL handshake error in the logs which suggests you're using a self-signed certificate meaning it won't be trusted by the application server JDK when making the GET request.

You can search here on Forum for this error for more information but basically the SSL handshare and the java.net.ConnectException: Connection refused: connect are not problems between APP_SERVER and MAIL_SERVER. Since this is failing even before sending the email, in the body rendering part, we can tell the issue is between APP_SERVER and WEB_SERVER in the GET request I describe above.

To fix this simply configure these two settings in custom.properties to point to HTTP and APP_SERVER. For example:

conf.suite.MAIL_SCHEME=http
conf.suite.MAIL_SERVER_AND_PORT=myappserver.mycompany.com:8080

and restart it. This way the GET request made by the app server will be made to itself and not the web server, which is indeed not required.

@Eduardo

Please find the attached custom.properties file related to mail server configuration settings and let us know if any modification required , so that will go ahead and restart Appian

custom (1).properties

I guess this is the sanitized version of your file for security purposes since the values look like dummy values.

In any case, as stated above, you need to set

conf.suite.MAIL_SCHEME=http
conf.suite.MAIL_SERVER_AND_PORT=localhost.xyz.com:8080

so they point to the app server

We still get the same error :
