I just noticed a strange email in my sent folder that I did not send. Here is the header information:
Date: Mon, 10 Jun 2019 06:54:17 -0700
Content-Type: text/plain; charset=UTF-8
This message was automatically generated by Gmail.
There was no content in the email, just the jumble of characters in the subject. The email address this was sent to is reported a few times on the internet as possible phishing, but it's not clear to me why Gmail would automatically generate an email on my behalf to this address. The "From" field was indeed my actual email address.
I have already changed my password as a precaution, but am curious is this anything to further worry about?
