Stop send email attempt when cron is run I just took over a drupal 7 site and when cron is run I get the follow error
SMTP Error: Could not connect to SMTP host
WD mail: Error sending e-mail (from ???????? to ???????)

I know the previous developer turned some feature/function on that will send an email each time a cron job is run.  Does anyone know how or where to turn this off?

I have checked in the admin-> cron, but there are no settings there to adjust.

Thank you in advance.
It's likely defined as a hook_cron implementation in a custom module. Trying searching through your codebase for "_cron" to see what you can find. If you install Elysia Cron you should be able to get a full list of all cron jobs and could disable any jobs you don't way run.
