I got a cryptic (or maybe just junk) message in my inbox today:
Delivered-To: <[email protected]>

Here's the body of the message:
d0wn by th3 drag0ns e\$tuary, wh!ch lay al0ng\$!d3 3d!ths 3!ght alpacas, n!n3ty-tw0 fact0r!3\$ pr0duc3d \$3v3n\$ 0f f!t \$!xty-\$3v3n\$
It just looks like spam to me, but I'm not sure, because there seems to be a sort of pattern here, but I'm at a loss. The subject asks "Who am I?", but it doesn't seem that there's anything here that says who they are. Can you help?
Hint 1
As I mentioned in the comments, every part (well almost) of the puzzle (the puzzle is everything in the code block, so you don't really have to look at the rest) is related to it somehow.
Hint 2
For example, the line: "Received: by 3166:673:a796:7652:f6a6:571 with SMTP id 6b7263675f61687a66;" contains a hint for the body's text.
Hint 3
Also, the last line of the puzzle, which seems like side-commentry, that everyone has chose to focus on, is also a clue, but, apparently, not a very good one, if that's the first thing that's noticed. It was supposed to be discreetly linking this puzzle to another, which has a (rather blatant) clue for this (and a deeper) part of this puzzle.
Hint 4
The numbers (and symbols) within words are there to confuse you. That said, (as I implied in the comments) you should be able to extract a hexadecimal number from the body and thereby (necessarily) a decimal one, for which the "From" hint will be relevant. The Signature hint is not relevant until you've figured out what the body means.
Hint 5
The "From" clue is meant to just point you in the right direction when it comes to solving the number. So don't think of specific things from The Mandalorian, but rather think broadly: what is The Mandalorian part of? I can say that you don't need to know anything about the Star Wars universe itself to solve this, though some info about the shows/movies themselves might be required.
Hint 6
It is a person
Hopefully this puzzle will be more difficult than the previous one I posted, which was solved in like 30 minutes 😑
I've accepted @Smartest1here's answer because it contains the right solution, though it's only a partial answer. @xhienne deserves credit, though, since they were the one who got to that point in the first place. See their answer for the reasoning behind the puzzle.
