I guess this e-mail is in fact legitimate. It is sent from the same mail address as the e-mail that I got last week, and all the data for wire transfer like name of receiver, address, bank name... are the same. The only difference is account number but I assume it is due to the fact that I am from Poland and maybe the have another account number for Polish.
Probably the account number for all foreigners is EUR account and for Polish is PLN account.
Wish u luck with your procedure
