Customer website has a gravity form with notifications setup to send out various emails. These emails occassionally fail to send.

The form in question does not have SMTP Settings…just a from address in the notification settings; the wp_config.php does not have any SMTP or other emailish defines. Where are the details that govern the email sending? I know that emails go out from a different provider than the web-host but I don’t know where those are setup.

Again, it does work often and the notifications logs say they were successfully sent but I can’t track the ones that fail without more info.
