If you receive a suspiscious email, do not click any links!
Obtain the email headers. In Gmail, if you click the 3 dots on the upper right side of the email, then click Show Original, you can copy the email headers there.
Forward the email you received, with the email headers you just copied added, to firstname.lastname@example.org. We will take appropriate action from there.
Delete the email you received. If you continue to receive additional suspsicious emails, continue to forward them to us with headers.
