FedEx scam email

I received email which suggests I have an undelivered package at a postal office.

I wondered why I receive this notice because I haven't bought any items recently from oversea and FedEx is not a major delivery service in Japan domestically. Then, I found FedEx alert message on the website. It is one of the infamous scam email. The email which I received did not attached any malicious files, but I need to be careful about this kind of emails.
