Cannot find source of email in Informix

We took over an existing Informix 12 instance. The logs are showing an email is being sent out after an update statistics job runs through a cronjob. I had a look at the script in the cronjob, and nothing is in there. Where would the configuration be for such a thing?

I misunderstood. This wasn't an email coming in. It was saying the job failed I think so disregard. I will look into the job.
