From mastodon to follow an account or a community on lemmy you use the @name@server format and there is no difference between a community name and a user-name

so i was wondering if anyone tried and checked what happened

I made an SMTP server that treats email addresses as case sensitive. When it gets mail for Philip@ponder.cat, it refuses to deliver it to philip@ponder.cat, and it allows users to create himbo@ponder.cat and Himbo@ponder.cat as two distinct addresses. Within my server, it's not confusing at all. Outside of my server, there be dragons.

You monster!

Now, what happens when one uses different cases in the domain part?

Round robin arbitration.

You joke, but gmail does this with dots in email. There is no difference to gmail between fartmaster@gmail.com and f.a.r.t.m.a.s.t.e.r@gmail.com. Not really any dragons here, but can create confusion if you're unaware.

Nah, Gmail does the exact opposite of what their server does. Gmail is extra lenient with how an address may look. While their server is extra strict.

Correct. Gmail is doing it right, by anticipating how their server's behavior might confuse people or lead to email going to the wrong mailbox, and making extra complexity to make sure the behavior makes sense. Lemmy is doing it wrong, in this instance.
