Completely OT:
is anybody else bothered by the use of capitalization in email addresses? I understand that it doesn't matter semantically, but I find myself thinking negatively of people who use this for some reason.
- userbinator 5y agoEspecially when it's Intel, the company which traditionally has a lowercase i in its logo. Also rather OT: The Intel l219 or I219 or i219 must be one of the worst names ever for a NIC. Even Intel doesn't seem to know whether that first letter is an uppercase I or a lowercase l.
- jupp0r 5y agoYes, I do know that theoretically there could be different mailboxes on a server that do depend on capitalization, but this is not really happening in practice as far as I'm aware.
- niij 5y agoThe RFC specifies that the local (left of the @) is treated as case sensitive[0] so it can have semantic meaning. In practice many hosted mail providers (Gmail, Yahoo, etc) treat their own accounts as case insensitive. But in MS Exchange, for example, you can have separate inboxes with only capitalization differences, so it's definitely not obscure. > local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". 0: https://www.rfc-editor.org/rfc/rfc5321#section-2.4 https://www.rfc-editor.org/rfc/rfc5321#section-2.4
- singron 5y agoGoogle even lower cases emails when they are used for calendars, so you need to assume case insensitivity for that api to make sense.
- jupp0r 5y agoThanks, I didn't know about MS Exchange. I still haven't seen this happen in practice (ie differently capitalized emails not arriving, etc).
