13/21 here. Mostly got hung up on several “this was valid in earlier RFC, and later removed” kind of situations. There are several where I picked the correct answer, but where I know many websites that won’t accept it as valid, and that’s not even the more esoteric ones.
But they will work, and according to the spec, you have to build your system so that it can handle those cases. Obsolete doesn’t mean incorrect or invalid, just a “you shouldn’t do this any more”.
Obsolete Syntax
Earlier versions of this standard allowed for different (usually more
liberal) syntax than is allowed in this version. Also, there have
been syntactic elements used in messages on the Internet whose
interpretation have never been documented. Though some of these
syntactic forms MUST NOT be generated according to the grammar in
section 3, they MUST be accepted and parsed by a conformant receiver.
Well shit, yeah, that “MUST be accepted and parsed” is pretty explicit. That sucks. What is even the point of revising standards? How the fuck do we ever get rid of some of these bad ideas?
Some of those “obsolete” things are outright blocked for specific reasons. For example, routing addresses through multiple servers. It was abused by spammers, so it’s almost always denied these days.
I scored 16/21 on https://e-mail.wtf/ and all I got was this lousy text to share on social media.
This was fun!
Edit: people, upvote the OP, not me
Don’t tell me what to do!

Yeah I feel like the correct answer for anything obsoleted by a more recent RFC should be “Invalid”.

Looks like this:
<@foo.example.com@bar.example.com:123@example.com>I got 14/21
Me too and it said that is the amount you’d get if you just picked “valid” for every response. Lmao
Samsies
Yay! Same. But only because I’ve already heard of some email craziness before.
yay 16/21 club
