Hey Race. As a public service to one of my Freeper FRiends, I have looked up the employee number in that email. I work at FedEx, and have access to look it up. There is no employee with that badge number. (179586)
This could tell you a couple of things. Which may mean you have little to worry about.
1) Someone using your address tried to send an email to this address, but it may not have come from your machine.
2) Since there is no employee 179586, the non-delivery notice is probably real.
I get emails all the time from random spam generators, and sometimes when I look at them, my email reader tells me that “this email did not come from the address shown”.
I have also been the victim of someone sending emails from “my” address, and get some of those undeliverable messages, just like you got.
According to my IT folks, these emails did NOT come from my physical location, but by someone using my email address from another computer. It can be done, and is not too uncommon. Think about putting your return address on a snail mail letter, and mailing it from another city. You know it came from somewhere else, but if the letter gets returned, where does it go? - Your house. Same for email.
I wouldn’t ignore it, but I wouldn’t lose any sleep over it, either. As it recommends in the Snopes article linked response #3 above, send an email to abuse@fedex.com if you like. Perhaps they can help.
You have freep mail
I downloaded the new Microsoft anti-virus and it is scanning the home computer now, some day it will be finished. :)
