How To/Validate email adresses using regular expressions

When your users register or have an other reason to submit their email address, you want to check if the mail has correct format.

The following code snippet shows validation by using the regular expressions with string.match.

function IsEmailValid(email) 
	return string.match(s,"^[%a][%w%.%-]*[%a%d]*@[%a%d][%w%.%-]*[%a%d]%.[%a][%a]?[%a]?[%a]$"))
end
