Thanks for you great answers, I am now looking into getting other email addresses as suggested, I have now found blocked sender list thanks to you, and as for blocking the whole domain, when these emails arrive they are always from *undisclosed recipients* so I don't know where they came from it seems I can only block certain names but each one is slightly different from the first for example Halifax email services, then it's Halifax online accounts, then Halifax electronic banking and so on...
