The error “Missing configuration parameter: ‘Mail/port’” could be due to the invalid port number given in the Mail Configuration of the Scheduler Administration tool. I would check if the following configuration properties are valid by doing the following steps:
1. In Scheduler Administration tool, check under ‘Server Configuration > Mail Configuration > Port’ has valid port number. Also, ensure that this is the port number that matches with the port number of Outgoing Mail (SMTP) Server.
1. In Denodo Platform files, check if the property ‘Mail/port’ in the <Denodo_Home>/conf/scheduler/ConfigurationParameters.properties file is also a valid one.
After verifying the ports, I would restart the Scheduler server and execute the job again to get the email with the output file sent successfully.
Hope this helps!!
