mi dai il codice completo?
come fai ad andare da connection a list?
uso un link, ho satmpato il vettore $_SESSION in connection.php e me lo scrive correttamente, il codice e' il seguente:

connection.php

codice:
<?php
	session_start();

	$_SESSION['user'] = "user";
	$_SESSION['pass'] = "password";
	
	print_r($_SESSION);
?>
<html>
<head>
<title>Connessione</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
	lista
</body>
</html>
lo script in list.php e':

codice:
<?php
	//session_name('name');
	session_start();
	
	$user = $_SESSION['user'];
	$pass = $_SESSION['pass'];
	
	$uid = $_GET['uid'];
	
	print_r($_SESSION);
	
	echo session_id().'
';
	echo $user;
		
	$mbox = imap_open("{pop.tiscali.it:110/pop3}INBOX", $user, $pass);
	
	$msgnumber = imap_num_msg($mbox);

function lista($mbox, $totnum){
	for($i=1; $i <= $totnum; $i++){	
		$overview = imap_fetch_overview($mbox, $i, 0);
		if (is_array($overview)){
			reset($overview);
			while (list($key, $value) = each($overview)){
			$uid = imap_uid($mbox, $i);
			echo "<tr>\n
					<td>".$value->from."</td>\n
					<td><a href=\"list.php?uid=".$uid."\">".$value->subject."</a></td>\n
					<td>".$value->date."</td>\n
				</tr>\n";
			}
		}//end if
	}// end for (scan of all messages)
}
?>
