I'm trying to fetch email from inbox using php imap(). In localhost function works fine but on our bluehost based dedicated server it showing following error
[an error occurred while processing this directive]
Php Code
$imap = #imap_open("{mail.******.com:143/novalidate-cert}", "a****i#*****.com", "******");
if(isset($imap)){
$message_count = #imap_num_msg($imap);
$array_mail = array();
if($message_count > 0){
for ($m = 1; $m <= $message_count; ++$m){
//$header = #imap_header($imap, $m);
$header = #imap_rfc822_parse_headers(imap_fetchheader($imap, $m));
$email[$m]['from'] = $header->from[0]->mailbox.'#'.$header->from[0]->host;

Can anyone kindly guide me where is the issue that i can fix. I would like to appreciate. Thank You.
EDITED
I added ticket to host provider. Following are the comments,
This error is because of a the FCGI timeout. This can be fixed by changing to suphp. You can change the php type in the whm to suphp on the Main >> Service Configuration >> Apache Configuration >> PHP and SuExec Configuration page. I suggest to closely watch the website with that to suphp as it makes the server more vulnerable to scripts running unchecked.
