I get these from time to time, fortunately I have a good spam filter. I forward them without opening to :
[email protected] - the IR do come back to from time to time to confirm that they are phishing emails, not from them. Don't be fooled, they look genuine but aren't! Likewise, the banks have a phishing or spam email address, and they ask for these to be reported to them so they can investigate. Get 'em all the time, usually in batches - dead giveaway if you don't have any account with that bank!
