Uczę się PHP5. Napisałem funkcję sprawdzającą czy działa serwer poczty. Z niezrozumiałych dla mnie przyczyn mam błąd:
  socket_bind(): unable to bind address [99]: 
  Cannot assign requested address
mimo że serwer poczty działa.
Proszę o wytłumaczenie.
Oto mój kod:

define('EMAIL_SERVER', '94.152.10.76');
define('SMTP_PORT', 587);

public function emailServerData() {
    if (($p = strpos(EMAIL_SERVER, ':')) !== FALSE) {
        $server = substr(EMAIL_SERVER, 0, $p);
        $port = intval(substr(EMAIL_SERVER, $p + 1));
    } else {
        $server = EMAIL_SERVER;
        $port = SMTP_PORT;
    }
    return array($server, $port);
}

// sprawdź, czy działa serwer poczty:
public function checkMailServer() {
    list($server, $port) = $this->emailServerData();
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    if (!socket_bind($socket, $server)) {
        return FALSE;
    }
    if (!socket_connect($socket, $server, $port)) {
        return FALSE;
    }
    socket_close($socket);
    return TRUE;
}
