Issue/Introduction

NCM has a functionality to trigger emails upon job completion.
However, there are times when these emails are not being triggered and this article explains a possible cause of this issue to look for. 

Environment

NCM 10.1.X

Cause

This issue could be because of the result-set size received upon the completion of the job. 

Look for messages in the following log on the Application Server:

Resolution

Please engage with your Network Team to check the permissible limits on the SMTP server and if these could be configured to allow larger result sets.

Alternatively, evaluate if you could reduce the result set size by running the jobs/tasks individually (instead of comprising of multiple devices into one job) to ensure that the email size drops down to the permissible limits.
