Hello,
Thank you for your feature request. I have noted it in our product backlog. In regards to why the message did not appear in the SMTP log, if it was sent through webmail, there was no SMTP connection in the first place. However, if it was sent through Outlook using SMTP, you should be able to see it in the log. The delivery log would contain all the necessary information since the message did not leave the server.
I hope this information helps.
Thank you.
