Jokes aside, I have been blocked many times by overzealous email validation. Yes, my email has a plus sign in it. This is allowed under RFC5322, so deal with it. It is better to have no validation at all than incorrect validation.

Even worse is when they strip the plus sign out after the fact and then you can't log in anymore because you didn't realize that's what has happened.

Yees this has happened to me before but with passwords. They have some length limit that they clamp to so you can't login after registering and I have to do a password reset right after signing up. Happened multiple times to me.

This is criminal. You already send me a validation email, just check for an @ and leave me be

A plus sign? That's nothing, LOL

I dont know if it's just me, but this comment is breaking the rendering of Voyager

[–] elvith@feddit.org 1 points 3 hours ago

I needed to use a code block for that address as several apps had a problem when I tested escaping the back ticks in the address for the inline code. Not sure if you mean that as it renders in it's own line or if anything else is broken

I like this issue in the form of a quiz

TIL:
🫱@🫲
is a valid e-mail address.

[–] smiletolerantly@awful.systems 3 points 15 hours ago

Nice, I was able to send an email to that.

[–] gegil@sopuli.xyz 74 points 1 day ago (1 children)

The best email validation is just sending an email to whatever provided by the user. If user receives an email and validates it, than its validated.

[–] kunaltyagi@programming.dev 7 points 15 hours ago

Email address spec is convoluted and this is indeed the best way. Noobs and ninja do it this way, normies try to validate before sending email

[–] dfyx@lemmy.helios42.de 55 points 1 day ago (1 children)

The worst sites are the ones that let you sign up with an unusual address but not log in. The worst I‘ve seen was some ticket system that rejected dfyx+theirdomain@mydomain after I clicked the link in their confirmation email.

There's an aspect of my surname which is somewhat unusual (at least in my country). As a result I occasionally get form validation errors when entering it. Sometimes those errors are extremely inscrutable. Sometimes a form validates but something elsewhere makes unvalidated assumptions about names which then breaks in completely unpredictable names...

[–] TurtleTourParty@midwest.social 14 points 1 day ago (1 children)

Does it fall into one of the falsehoods programmers believe about names? https://www.kalzumeus.com/2010/06/17/falsehoods-programmers-believe-about-names/

[–] FishFace@piefed.social 2 points 16 hours ago (1 children)

Actually no. In fact, I think most people who thought for a minute would realise names like mine exist, it's just that sometimes people working systems don't think for a minute ;)

[–] purplemonkeymad@programming.dev 4 points 5 hours ago

The number of scripts I've seen that would break with an O'Neill or O'Brien is too high. Worse is some people don't get it when pointed out.

I had a website not let me enter a proton.me email address, when I changed it to my custom.fyi address, it worked fine. They wanted a three letter TLD.

[–] Scrollone@feddit.it 9 points 17 hours ago

No, I think they just blocked Proton email addresses. I've seen multiple services doing that.

[–] traxex@lemmy.dbzer0.com 7 points 1 day ago (2 children)

Not sure if you also do aliases as well but I’ve seen an increase in websites flagging providers like addy.io as well. Extremely annoying that so many websites think they are so important that they refuse an alias.

[–] borari@lemmy.dbzer0.com 7 points 20 hours ago

I had a site refuse my email address for my .net domain. Like wtf, if it’s not .com it’s not a real email address? Idk what that was about.

[–] grendel84@tiny.tilde.website 4 points 19 hours ago

@traxex
@ooterness

migadu has a cool workaround.

instead of:
alias+user@domain.tld

you give:
alias@user.domain.tld

then internally it transforms it to an alias when it comes in.

[–] Scoopta@programming.dev 7 points 1 day ago

Same although for a totally different reason. There are some services that really don't like gtlds and they will say your address is invalid if it doesn't end in .com, .net, or .org...all my serious domains are gtld...so some services have emails on meme domains because the only domains I have with traditional tlds are memes
