Everyone knows what an email address is, right? (Quiz)
-
Question 5 is incorrect,
name@exampleis a fully valid email address, even after RFC 2822The spec of RFC 2822 defines an address (3.4.1) as:
local-part "@" domaindomainis defined (3.4.1) as:domain = dot-atom / domain-literal / obs-domaindot-atomis defined (3.2.4) as:dot-atom = [CFWS] dot-atom-text [CFWS] dot-atom-text = 1*atext *("." 1*atext)1*atextmeaning at least 1 alphanumeric character, followed by*("." 1*atext)meaning at least 0"." 1*atext
If tomorrow, google decided to use its
googletop-level domain as an email domain, it would be perfectly valid, as could any other company owning top-level domainsGoogle even owns a
gmailTLD so I wouldn't even be surprised if they decided to use itwrote last edited by [email protected]I didn't understand this one. How do you have a no dot domain? Like you need to distinguish from example.com or example.wtf
Edit: do you mean if you own
.googleyou can have youremail@googleaddress? -
You gonna fill an IPv6 address for your email server into the DoorDash signin page?
Don't be ridiculous, I'm going to use an open source password manager to fill an IPv6 address for my email server into the DoorDash signin page.

I did not like this and quit after ten questions
But I respect that it exists.

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 know you're being facetious, but I'm thinking through the implications of someone actually doing this. ISPs aren't always handing out static IPv6 prefixes for some damn reason, so you can't count on that address staying the same when self-hosting. Even if you can, you don't know what will happen when you change ISPs.
So yeah, really bad idea regardless.

Almost correct. ^.+@.+$
Too hard to validate properly to be worth it. Even if it is technically valid that's insufficient. It must also work, and the easiest way to test that is to use it and verify that the user got what we sent.
I see you accept lemmy handles.

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? -

if i can email them and the user gets it - fine by me

If qoutes are removed and internal spaces are invalid, how could
":(){␣:|:&␣};:"@example.combe valid?Presumably the space between quotes is "escaped", meaning it's supposed to act like any other character.

":(){␣:|:&␣};:"@example.combe valid?Not too sure, but a previous one says spaces are allowed in comments. I would assume the
{}is similar? -

17/21. Would have been 18 but the first example of spaces screwed me.

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.

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

Yeah they're processed, but not passed through.
