imap_open (Internet Message Access Protocol) Problem

What are the server settings for the imap functions on webzdarma? The line below gives the listed warnings.

$mbox = imap_open("{".$servername.":110/pop3/notls}INBOX", $username, $password);

Warning: imap_open(): Couldn't open stream {webzdarma.cz:110/pop3/notls}INBOX in /3w/wz.cz/x/xxx/xxx/xxx/xxx.php on line 26

Warning: imap_check(): supplied argument is not a valid imap resource in /3w/wz.cz/x/xxx/xxx/xxx/xxx.php on line 34

Well, I guess you mix pop3 and imap ports.

TCP Port 110 - POP3 (Post Office Protocol version 3)
TCP Port 143 - IMAP (Internet Message Access Protocol)

First, try to modify argument "110/pop3/notls" on line 26.

Server settings at webzdarma (taken from phpinfo):
imap
IMAP c-Client Version 2000
SSL Support enabled

I modified the argument with the imap_open() examples below but I am still getting the same warnings.

<?php
// To connect to an IMAP server running on port 143 on the local machine,
// do the following:
$mbox = imap_open("{localhost:143}INBOX", "user_id", "password");

// To connect to a POP3 server on port 110 on the local server, use:
$mbox = imap_open ("{localhost:110/pop3}INBOX", "user_id", "password");

// To connect to an SSL IMAP or POP3 server, add /ssl after the protocol
// specification:
$mbox = imap_open ("{localhost:993/imap/ssl}INBOX", "user_id", "password");

// To connect to an SSL IMAP or POP3 server with a self-signed certificate,
// add /ssl/novalidate-cert after the protocol specification:
$mbox = imap_open ("{localhost:995/pop3/ssl/novalidate-cert}", "user_id", "password");

// To connect to an NNTP server on port 119 on the local server, use:
$nntp = imap_open ("{localhost:119/nntp}comp.test", "", "");
// To connect to a remote server replace "localhost" with the name or the
// IP address of the server you want to connect to.
?>

I searched webzdarma's FAQ and found an explanation:

E-mail on webzdarma is only accessible through the web interface The other choice is setting email forwaring. Both can be done in "administrace".

That means that pop3 or imap function are NOT supported by webzdarma.
