email Validation

[kschuster]

Has anyone scripted for validating an email address directly to the mail server?

i found this function on some other website (forgot which one)
it works for me, but not on the server of a friend.
[/code]
function check_mail($email) {
$test_mail=eregi('^{[a-z0-9-]+(.[a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)+$',$email);}

if ($test_mail) {

list ($login, $domaine) = split ("@", $email,2);

if (checkdnsrr ($domaine, "MX")) {

return TRUE;

}

else {

return FALSE;

}

}

else {

return FALSE;

}

}

function check_mail($email) 
{ 
	$test_mail=eregi('^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)+$',$email); 

if ($test_mail) 
{ 
	list ($login, $domaine) = split ("@", $email,2); 

	if (checkdnsrr ($domaine, "MX")) 
	{ 
		return TRUE; 
	} else 
	{ 
		return FALSE; 
	} 
} else 
{ 
	return FALSE; 
} 

}

I just posted your code so i can read it with colors 🙂

thanks!! 🙂
