Today I was asked if my email was all lowercase or uppercase. I wanted to be sarcastic but I relax this time.

I don't understand why only lowercase and uppercase why not camelcase?

It's Pascalcase obviously

Snake

Actually it depends of your domain provider, if you are using one of the major aka gmail /microsoft... Its not case sensitive however a more local one or even your own webmail could be (i really doubt it tho). So the question is legit if you are providing a unusual domain or top level domain name (aka everything behind @).

RFC 5321, section-2.3.11

@hube learned something new there. Thanks!

@hube In my case I had @gmail.com. Will research on your comment.

Why not hungarian?
