Sign up with invalid email

Idk if I saw it here on meta or somewhere else. There was a topic about having invalid emails by adding +invalid or somthing similar to email. I cant find it now and need help.

the format is something@something.invalid

Can you show me the topic? I want to see the details and use cases.


You might get better help if you describe what problem you’re trying to solve.


I want to find a practical way to let ppl signup with their mobile number in my application, that is bundled with discourse.

So as far as I see, no email is send to this invalid email from discourse yes?
