Admin Notifications are not sending, regardless of what email address I'm sending to. Emails are sending out to users. I've been in contact with my host, and set up the WP SMTP plugin with the options they provided. They have helped me set up the correct MX records, as we recently transferred registration/hosting to them, so all of that is correct. They suggested Google SMTP for an outgoing server, but as of this writing, I have not located those options on our Google Apps mail.
We do have logs of each of the test emails in the dashboard, but server admin can only see one entry in the email log. They did not find any blocked emails on the server that could be causing the issue. Host says next step is to contact you. Please advise anything else that I should try, or if you are familiar with Google SMTP. I can find options for incoming mail, but not outgoing mail from the Google Apps dashboard.
