Subject RE: Nifi- PutEmail processor issue
Date Tue, 15 Nov 2016 09:07:09 GMT
Thank you for your reply.

My requirement is , I just try to send/copy the 3 different files from source to destination
through Nifi, and these jobs runs weekly once.
So I wanted to know which file is successfully moved through email.
In this process, I have configured putemail for each flow. There are hardly 3 notifications
Though files have been moved to destination, we could not receive the notifications properly
and giving the below error.

Please suggest.

Hello Sravani,

Could it be possible that the SMTP server you're using is denying connections due to the volume
of emails your flow might be sending?  How many emails are sent per flow file, and how many
emails do you estimate are sent per minute?

If this is the case, you can modify your flow to aggregate flowfiles with a processor like
MergeContent so that you can send emails that resemble a digest, rather than a separate email
for each flowfile that moves through your flow.

I have used PutEmail processor in my project to send email notification for successful/failure
copying of a files.
Each file flow having corresponding PutEmail to send  email notification to respective recipients.

Here the issue is, sometimes email notification will send to respective recipients successfully
 for successful/failure job.
But sometimes for any one specific job email notification will not be send to recipients though
job is successful, due to  below error.


Could not connect to SMTP host Connection timed out

Could you please suggest me how we can overcome this error.
