But as this article points out - that's not always helpful when the company makes it difficult to contact them - or in this case, the Duty and Taxes [sic] aren't a part of the FedEx process but a part of the government, so to FedEx it's a third-party issue and so when they pulled up the shipment, no mention was made of it (that's my theory why that happened).

Your advice is good - I'm just saying it won't always work. heh. But it is the thing you must do unless you recognize the message source/content and even then, better to just log in separately. heh
