I was trying to log in to a crypto exchange site that I have not used before but could not as no confirmation emails ever arrived. Troubleshooting led me to the source of the issue, which was Filters set to delete all emails from that domain.
The thing is I never set these filters up! In the screenshot there are some e exchanges I've heard of or even have an account but some I never even heard of so could not have added a filter for.
The question is how did this happen? If someone hacked y account what would be the purpose of this? I really cannot think of the motivation for a third party to delete these emails specifically. I did recently change the password as there was unauthorized access from an app though I saw not other IP's accessing my account so not sure why gmail warned me. Is there anything I am missing?
