Oldie but a Goodie… Here’s The Info Guys!
From the Fedex Website:

Virus Alert

Be alert for fraudulent e-mails claiming to be from FedEx regarding a package that could not be delivered. These e-mails ask the receiver to open an attachment in order to obtain the airbill or invoice for picking up the package. The attachment contained in this type of e-mail activates a virus. DO NOT OPEN the attachment. Instead, delete the e-mail immediately.These fraudulent e-mails are the unauthorized actions of third parties not associated with FedEx. When FedEx sends e-mails with tracking updates for undeliverable packages, we do not include attachments.

FedEx does not request, via unsolicited mail or e-mail, payment or personal information in return for goods in transit or in FedEx custody. If you have received a fraudulent e-mail that claims to be from FedEx, you can report it by forwarding it to abuse@fedex.com.

If you have any questions or concerns about services provided by FedEx, please review our services or contact FedEx Customer Service.
