My bank has implemented suggestions I've given them in the past (USAA), but recently they used a different domain for a legitimate-seeming email (the email was about something I just did, and it was to an address I only use with that bank), and I called them up and spoke with someone in their fraud department to ask about it. I told them either they were hacked, or they were training their customers to fall for phishing, and asked them to create a ticket.

They said that domain name was not theirs, and they only use usaa.com in their emails. They locked my account without telling me. I had to call them back to get them to unlock my account, and I think that person in their fraud department understood the issue and they said they created a ticket.

We shall see...
