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!
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.
Yeah I feel like the correct answer for anything obsoleted by a more recent RFC should be "Invalid".
Complaints about the quiz? Send them to 💩@💩
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".

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.

Me too and it said that is the amount you'd get if you just picked "valid" for every response. Lmao
