Someone should beat some sense into him with a hammer made of Norwegium.

Yes, 4 is Death, so if a hotel has a 4th floor, it’s westerners who get those rooms, while the luckier Chinese get the 8th. Sure, that’s superstitious, go complain to the folks on the 13th floor.

I deal with the email validation nonsense a lot, because I have several email systems that usefully support username+tag@domain.com (or for some systems, username-tag@domain.com), and one of them even translates between that and tag@username.domain.com, so you effectively have an arbitrary number of email addresses in your subdomain as part of one email account. And there are too many web forms that ask for an email address, and reject the version with the + in them.

It’s true, the + has been part of the email address standard since the beginning and it has a longstanding reputation as the most neglected in validation checks. Of course all bets are off now that people can register unicode domain names…

http://💩.la for example.  one could have the email address 💩@💩.la
or http://☃.net or http://🚚.la it is a crazy new world out there

(sorry had to wrap the above in a code tag to keep the bbs from breaking the emoji domain names…see the issues these cause…even here, where the code is well constructed. paging jeff @codinghorror )

Of course there are issues with certain parts of the unicode set enabling homograph attacks:

which is why most registrars only allow registration of subsets limited to specific languages.

I’d have to read the current RFC’s, and I’ve got too much to do this morning before breakfast. RFC 822 is obsoleted by RFC 2822, which is obsoleted by RFC5322, which is updated by RFC6854. (Then there’s the matter of how vendors implement RFCs.)

Happy reading…

yeah, apparently this is a valid address: some.guy(hey.guy!)@some(hello.this.is.a.comment.for.some.reason)domain.com

Gmail doesn’t like it.

Well, that’s interesting, because when I visited Edinburgh they thought the Scots had invented it – Edinburgh being the original example. In Canada heavily gridded street plans often have a story about super-organised Scottish surveyors, apocryphal or not.
