thanx mark. i missed that. i got a list of top levels and added those to check against that. i knew about the two letters and to make that easier used \w\w, but apparently \w\w\d? is what i should have there.

What about IPs? I'm pretty sure you can email a user@IP.

Read section 4.1.3 of RFC 2821.

i've been using this forever:

function validate_email(&$email) {
	if(	preg_match("/(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/",$email) ||
		!preg_match("/^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/",$email)
	) return 0;
	return 1;
}
