What is the best regular expression for validating email addresses?

I have the following expression

**replacePattern3 = /(\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,6})/gim;
   replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>');**

but it doesn't validate email if the email in this form [email protected] it only validate email in form [email protected]

i need another expression to validate the form [email protected]

I think \w+ is the same as [a-zA-Z0-9], so it doesn't like the dot. I'm not good at this, but try

**replacePattern3 = /(\[a-zA-Z0-9\.]+@[a-zA-Z_]+?\.[a-zA-Z]{2,6})/gim;

You also might want to add a few more symbols to most places, because domain names can have numbers and certain symbols in them.
