I have this code to sand email:


function sendEmail($to,  $title,  &$text) {
     $from = '[email protected]';
     $subject = $title;

     $w = '<html><head><meta http-equiv="content-type" 
content="text/xhtml; charset=utf-8"></head>
            <body 
style="background-color:#ffffff;color:#000000;margin-top:30px;margin-left:30px;padding:10px;"><hr><br>'
           . $text . '<hr><br><p><a href="mailto:'
             . $from . '">' . $from . '</a></p></body></html>';

     $he = 'MIME-Version: 1.0' . PHP_EOL . 'Content-type: text/html; 
charset=utf-8 ' . PHP_EOL
               . 'From: admin Search. <' . $from . '>' . PHP_EOL
               . 'Content-Transfer-Encoding: base64' . PHP_EOL;

     $w = chunk_split(base64_encode($w));
     imap_mail($to, $subject, $w, $he);
   }


how to catch this error

Warning: imap_mail(): Failed to connect to mailserver at "localhost" 
port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use 
ini_set()

thank for answers
