Here's the situation.
We've got an online application, with a place where people can register (Supply their name, email, etc).
Some fella is complaining that it won't accept his email address. After looking into it, turns out his email address is email@example.com. It's got an apostrophe in it.
I've never come across this before! The validation we've got doesn't allow that sort of punctuation.
(To avoid blame, I personally didn't write this application, although I must admit I would have done it exactly the same way!)
My question is - is it common for email addresses to contain apostrophes? Or am I allowed to tell him to get a proper email address (allocated to him by his company)? I don't mind modding our application to allow this, but if this is going to be a one-off, I don't know if it's worth my effort.
I've hunted around for specifications on what email addresses can contain, but no joy. If anyone's got one, please sticky me if you can't post it!
(Forgive me if this is in the wrong forum...I tried my best!)
