A little quirk of UIDs in a PUBLIC folder in MDaemon (and perhaps other servers?). The UIDs may be unsynchronised between users if the server's option to store flags on a per-user basis is turned on. That is, a message may have a UID of 5 for one user (meaning it was the 5th message to enter the box) but 3 for another user (who perhaps subscribed to the box later). If this is a problem, turn off the per-user option for the mailbox.

Please note that message_id in the header is NOT the UID - and its dangerous to use as many mail progs don't put a message id in

Another way to get the UID without using imap_uid that works with pop3:



$header = imap_headerinfo( $mbox, $msgno );

$UID = $header->message_id;

For those using a POP3 mailbox, this function, as noted, does not work.





One way around this is to use direct FTP communication with the mail server.  For example, the following function takes a mailbox/password and message sequence number, and from this returns the message UID.





function fetch_UID($account, $password, $message_number)


{


    $retval = 0;


    $fp = fsockopen($POPMAILSERVER, 110);


    if ($fp > 0)


    {


        $buf = fgets($fp, 1024);





        fputs($fp, "USER $account\r\n");


        $buf = fgets($fp, 1024);





        fputs($fp, "PASS $password\r\n");


        $buf = fgets($fp, 1024);





        fputs($fp, "UIDL $message_number\r\n");


        $retval=fgets($fp, 1024);





        fputs($fp, "QUIT\r\n");


        $buf = fgets($fp,1024);





        fclose($fp);


    }


    return substr($retval,6,30);


}





Note: 110 is the TCP port commonly associated with a POP3 mailbox.  Also the substr() function is used to trim the +OK and the message number from the beginning of the server's response.





I'm sure there are other (better) ways to do this.  But after a fruitless search of the internet, this is what I came up with, and it seems to work for me.
