I tried to submit a request on behalf of a customer who is also the reporter. I thought once a ticket/issue was created in JSM whoever comments on it would automatically trigger a support email to them.
I first found that I needed to turn off the exclude person who caused the action.

I have tested it with another email address and it works fine.
but I have an existing ticket I'm trying to get to send an email and the log shows all my test ones before and after changing that option work, but for some reason emailing this particular customer domain after making the ticket on their behalf won't send.


I tried following this links instructions so far and didn't work for me sadly
