.IsValidEmail() reporting incorrect results about z.extensionmethods HOT 4 OPEN

If you really want to make it validate email addresses, RegularExpressions probably isn't the way to go. The simplest way to cover everything would probably be to just try creating a new MailAddress object and catch if an exception is thrown OR re-implement the code that does the email address validation from the .NET framework (https://github.com/microsoft/referencesource/blob/master/System/net/System/Net/mail/MailAddressParser.cs)

Hello @jasenf ,

Do you have a proposal to the Regex we should use? Last time I made a research about it, pretty much all regex has some flaw and it seems there is no consensus about which Regex to use.

Best Regards,

Jonathan

I think it's fine as-is if you just allow the + sign.

We will try to review it soon by using the syntax from here: https://en.wikipedia.org/wiki/Email_address

It will not be perfect but we will change the regex to at least contains printable characters (which contains the plus sign)
