Every once in a while I don't receive an email notification for a form submission, but in most cases I do. I have alternately used the default wp_mail(), WP SMTP by Callum Macdonald and Configure SMTP by Scott Reilly, using both my host's SMTP server and Gmail, various ports, SSL and not. Results have varied but it is always so intermittent that an email won't arrive I never know if it's from the choice of plugin or some other random bit of information.
So, I am wondering if there is a way to turn on debugging or at least log mail being sent by Gravity Forms, to troubleshoot this more thoroughly and maybe find out where the email delivery sometimes fails.
Thanks
