Geting Mail Messages From IMAP to UNIX mail file ???

I need a solution to get messages from IMAP server transfered over to my
server. Once the transfer complete I want to be able to read them. And one
more thing this script has needs to run from cron.

So far I figured out to get messages from the IMAP . Here is my code in the
nutshell.
Email message and attachements get transfered correctly however when trying
to read the file created with "mail -f file" it tells me that there is 0
messages in that file even though I know there is at least 10 messages.

how can I write these emails to the file and be able to read them later.
????

$mbox = @imap_open("$MAILSERVER$MAILBOX",$IMAPUSER,$IMAPPASS);


if (!$mbox) {
/* If $mbox does not exist it means that connection
to the server was not established
we need to report this issue */
$error = "phpMailArchive IMAP CONNECTION FAILED";
$err_body .= 'phpMailArchive was not able to connect to' . $MAILSERVER ."
\n\n ERROR: \n". imap_last_error() . "\r\n";
report_error($error,$err_body);
@imap_close($inbox);
exit;
}

$total = @imap_num_msg($mbox); //Get Total Number of messages
