Receiving-Reading mails using imap

Hi all,

I was searching for script to read emails any mailserver, like gmail, yahoo etc using imap. I came across many example scripts using imap, but unfortunately the connection CANNOT be established to the webserver even I have imap enabled . One of the scripts I tried

#### CODE ####

<?php
$user = “username”;
$pass = “password”;
$connect = @imap_open(“{localhost}INBOX”, $user, $pass) or die(“Connection to server failed”);
echo $connect;
$headers = @imap_headers($connect) or die(“Couldn’t get emails”);
$numEmails = sizeof($headers);
echo “You have $numEmails in your mailbox”;
imap_close($connect);
?>

#### CODE ENDS HERE ####

I cant get connected to any server here! What does actually the code means? Here, in imap_open functions, the first parameter is {localhost}INBOX”. To which mail server do this is intendend to connect ? What should I do, If I need to connect to gmail or yahoo, by providing username and password ?

Please help/guide me . Thanks for all of your time,

Regards,
Subeesh
