I'm completely agree with mr. L. Beck, actually to Mr. Austin's point of removing useless regexes, you often learn more from a broken expression than from a working one!

That's what the rating and comment systems are for. There are dozens of email validation regular expressions here. I expect most people to use the ones that have the best comments and highest ratings.

Using this regular expression on an order form, could lose you a sale! museum@museum.museum could be a valid email address, but this RegEx won't match it. Therefore it is useless. Please remember, it's better to let an invalid email address get through than block a valid one. I wish the site moderators would go through their database and remove useless regular expressions like this one.
