Cringe take, but fair enough on the bank freaking out part.
My interaction with them went like this:
>staff: And what's your email address?
>me: $BANK_NAME@$MY_DOMAIN
>staff: chuckles
And on the next day I got my bank account flagged.
Edit: Turns out the restriction was not related to the email address. It was a red Canadian bank.
I would say large banks like Citibank, DBS or HSBC would never care to this since all external emails are written to have a huge 'EXTERNAL' in the subject and a disclaimer before the content.
