Lately I have been receiving unexpected validation/confirmation mails from various social media and/or e-commerce sites, asking me to validate my account or giving me the overview of my last order. I never registered to those social media, nor I ordered items on that site.
I checked all the usual suspects for a scam mail (hyperlink previews seem legit, grammar and syntax is ok, etc.), the only thing these mails have in common is that at the very end they have the disclaimer
This mail has been sent to email@example.com [...]
while my address is firstname.lastname@example.org
Are these real phishing mails, or is it a problem with how Gmail addresses the mails?
