I received this email in my inbox:
It seems innocuous enough and the source of the message tends to confirm this:

Based on the information shown above, I have come to the following conclusions:
The SPF test passed, confirming that the IP address my mailserver received the message from is authorized to send emails for that domain.
The message doesn't contain any links or URLs.
Am I missing an attack vector here? Is this an attempt at phishing? If so, what is it that I am supposed to be tricked into doing?
