Almost all of them had people leaving comments about how it failed to validate or invalidate some rare but completely valid/invalid address syntax. But dispite all the criticism, I couldn’t find a definitive “best” expression. So, I setup arrays of some of the most promising expressions as well as a (hopefully) complete sampling of valid and invalid addresses and found the best regular expression to validate an e-mail address.
