I have all alerts of this type set to go to my "Alarm" group:
I have tried sending email from both Outlook and from a Windows command line utility called Blat. I pushed the formatting to MIME to make sure there wasn't any HTML formatting. There are no external signatures, only text from Outlook, and none when sending from the command line.
I haven't started Orion alerts as the email was my main push at this time.
New log bundle is included.
Thanks so much.
