Definitivo. Errore bassissimo.

$pattern = "/^([\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+\.)*[\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+@((((([a-z0-9]{1}[a-z0-9\-]{0,62}[a-z0-9]{1})|[a-z])\.)+[a-z]{2,6})|(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?)$/i";
 
if(preg_match($pattern, "[email protected]"))
     echo "ok";

Please don't use this for email validation. It fails for so many valid email addresses. Take, for example, a google address with a tag:

[email protected]

Its a perfect valid email address but the regex fails it. A regex CAN'T properly validate an email according to the RFC, and if you really want to learn how to do it properly, read:

maybe you are right, but i need a validator very strict. if it fails for a valid email, the user can always contact me and convince me his email address is valid!
