on Server - "Send test email" works; using Send Mail operator does not

Status: Investigating

Using RM Server 8. When I send a test email in System Settings, it works fine. When I use the Send Mail operator in a process run on the server, it does not work.


I added com.rapidanalytics.mail.jndi_name = java:/Mail to the config files under job-agent (and job-agent sub folders) to see if that would work - even though it's redundant - but nothing. Also, if I run the process in RM Studio on same machine (with same settings that were used in RM Server setup), it works.


Log is attached.


Please advise. Thanks.

I've been able to reproduce your problem. I can confirm that this problem wasn't present in Server 7.6.


We are working on a solution.


Thank you for your post!

As a workaround:

  • copy your local /home/username/.RapidMiner/cipher.key file into the RapidMiner Server/job-agent/config/container/.RapidMiner folder
  • copy the following lines from the /home/username/.RapidMiner/rapidminer-studio-settings.cfg to the RapidMiner Server/job-agent/config/container/container.properties file:
    • rapidminer.tools.mail.sender
    • rapidminer.tools.smtp.user
    • rapidminer.tools.smtp.passwd
    • rapidminer.tools.smtp.host
    • rapidminer.tools.smtp.port
    • rapidminer.tools.smtp.security
    • rapidminer.tools.smtp.authentication

I encountering the same issue, seems like RM8 server can't apply the smtp host & port in /standalone/configuration/standalone.xml. So using the default smtp host & port as localhost & 25 alternatively.

<outbound-socket-binding name="mail-smtp">
     <remote-destination host="smtp.office365.com" port="587"/>

hello - status is that it's still in the JIRA queue with the dev team. "Upvoting" here on this forum will definitely send signals about prioritization.

The "work around" works well for us.   If you take the settings that used to go into standalone.conf and place them into each job agents container.properties   as 

rapidminer.tools.smtp.host = somehost.com

rapidminer.tools.smtp.port = 25

The send mail should work just fine from server and will not use localhost.
