Emails like that, do not have a body, only headers.
What makes them unique is the content of those headers:
"From" is always the following:
Code: Select all
From: [email protected]
What makes it different this time, is that the email that I've lost, was a new post notification of a forum that is hosted on my server.
By comparing it's timestamp and the forum posts that was made at that time, I've managed to figure out for what post the notification was.
Unfortunately I can't always guess the content of the empty emails I am receiving.
