I kind of expected a lot of this; I remember the sendmail 4 book from back in the day when O’Reilly had that, DNS and BIND, and Perl as the entirety of its corpus.
I
rage quitgave up at 12.A fork bomb is apparently a valid email address.
I quit, this is stupid.
13/21, seems like I am not significantly different from random guessing
Got the same, I can’t believe how many weird comments and extra random things can get added into an email address.
I scored 16/21 on https://e-mail.wtf/ and all I got was this lousy text to share on social media.
I feel pretty good about that
nice. though valid but obsolete is not a thing… if it’s obsolete it’s invalid.
Agreed! (because then I would get 3 more points on the test)
Also as the registrant of one of those new fancy TLDs, much like the owner of this website (email.wtf), their own email addresses will fail those stupid email validation checks that only believe in example@example.[com|net|org]
Shitty websites will fail “example@email.wtf”, guaranteed - despite it being 100% valid AND potentially live.
Source - I have a “.family” domain for my email server. Totally functional, but some shitty websites refuse to believe it.
I’m not sure I blame the sites. The spec is so complex that it’s not even possible to know which regex to use
const emailRegExp = /^[\w.!#$%&'*+/=?^`{|}~-]+@[a-z\d-]+(?:\.[a-z\d-]+)*$/i;per the HTML specification. From https://developer.mozilla.org/en-US/docs/Learn_web_development/Extensions/Forms/Form_validation#validating_forms_without_a_built-in_api
That’s one very random place to find that. There are a lot of different one and there is no way we all just agree to use that one.
Look art his site that shows a more complete and (in theory) official website. While also explaining that there is no regex that is perfect
(Compete regex for the lazy)
(?:\[a-z0-9!#$%&'\*+/=?^\_\`{|}\~-]+(?:\\.\[a-z0-9!#$%&'\*+/=?^\_\`{|}\~-]+)\*|"(?:\[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\\\\[\x01-\x09\x0b\x0c\x0e-\x7f])\*")@(?:(?:\[a-z0-9]\(?:\[a-z0-9-]\*\[a-z0-9])?\\.)+\[a-z0-9]\(?:\[a-z0-9-]\*\[a-z0-9])?|\\\[(?:(?:25\[0-5]|2\[0-4]\[0-9]|\[01]?\[0-9]\[0-9]?)\\.){3}(?:25\[0-5]|2\[0-4]\[0-9]|\[01]?\[0-9]\[0-9]?|\[a-z0-9-]\*\[a-z0-9]:(?:\[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\\\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\\])
I have plenty of website reject even my fairly vanilla [email]+XYZ@ address add–ons
I have a spam collecting address @freemail.hu , the domain is live and working since 96, sometimes it’s not accepted, because it’s not Gmail I guess
Same as I have a .party domain. So I made a place holder (looking at you progressive) email ___+haslazydevs@gmail.com
Yeah I have a .engineering for my biz. I also registered mycompanyengineering.com to get through places that won’t take the new TLDs.
Usually banks.
Seems like a weird choice as the primary TLD.
I’d switch it just to reduce the annoying typing hassle and to avoid misspelling.It’s already unusual if I say “My email is givenName@LastName.eu”
And that trips so many persons.
First: I have my own domain
Second: It’s not gmail, apple or a local provider
Third: The TLD isnt.deor.combut.eu
Let us recite the email validator’s oath:
If it has something before the
, something between theand the., and something after the., it’s valid enough.The ultimate validation is to see if it gets sent.
Fails for when there is no TLD. Just send an email and validate a response eg from a link.
No. The number of users who have a real email with no TLD is far less than the number of users who will accidentally type an email with no TLD if you don’t validate on the front end.
I’m here to help 99.9% of users sign up correctly, not to be completely spec-compliant for the 0.1% who think they’re special.

I actually died at the poop emoji one. Actually amazing awareness to test for that
12/21. It was highly entertaining though.
I lost it at the fork bomb. I mean I hit valid because there was no way it was on the and not valid, but there’s no way i’d have expected that. after that I just kept guessing the most stupid answer and did pretty well
I gave up when I got like 5 wrong. I’ve ran mail servers for decades, most of the invalid “valids” would get rejected by any mailservers I’ve administered.
Just because it’s not something you’d use anymore doesn’t mean it isn’t valid.
WEP is still a valid form of wireless encryption, but no one would use it anymore (and so would be obsolete). It’s still a part of the 802.11 standard.
And for a good reason.
I don’t care who the IRS sends, I am not validating emails with spaces on them.
You shouldn’t be validating emails yourself anyway. Use a library or check for only the
and then send an email confirmation.Even if it’s a completely valid address and the domain exists, they still might’ve fat fingered the username part. Going to extreme lengths to validate email addresses is pointless, you still have to send an email to it anyway.
I seem to have annoyed an admin of an instance enough for them to subscribe my signup email to hundreds of dating profiles (presumably using a service that offers to harass someone for you)
Many of them aren’t good at validating email
One in ten has one email arrive, asking me to click a link to confirm
9 in ten have 5 emails before I notice them:
- Please click a link to confirm
- You received a wink
- You received a wink
- You received 3 chat requests
- You received a link
So it’s important to not send emails beyond the validate one to unvalidated addresses, to perfect your service annoying or harassing this parties
Also, use a disposable address for signing up to Lemmy
This is the way.
And after that, I now can’t wait for the next pull request with a regular expression on email validation to come through.
12/21
are things that are considered out of current spec really “valid” though?
And is it really valid if my email provider doesn’t accept it? If it’s not universally accepted or standard, then it doesn’t matter if it’s technically valid.
The RFC is the standard.
If your email provider doesn’t accept email@email.wtf is it then invalid?

Damn, and here I thought I had this locked down because I was salty that so many places struggle with
+in the email addy. But my god, there’s comments?
