    By using imap_fetchbody() you may run in trouble by using too much memory. Using imap_savebody() may prevent this. 
    But the content will be encoded, in other words it is useless. Adding a filter can help here.
    <?php
    $whandle = fopen('./incomming/tmp.tif','w');
    stream_filter_append($whandle, 
      'convert.base64-decode',STREAM_FILTER_WRITE);
    imap_savebody ($mbox, $whandle, $i, $partcounter++);
    fclose($whandle);
    ?>
    NOTE: To find the proper filter you need to check the encoding given by the structure of the body.
    This function will save ALL information from the email if the part number is left out. Pretty handy for archiving.
    It seems that imap_savebody saves attachments with special characters above ascii 127 as quoted printable. 
    But if you need it in utf8, you may use the imap_qprint function after the attachment is saved:
    <?php
    $tFile = "/path/to/attachment";
    $tFileOutput="";
    $tFileHandle = fopen($tFile, "r");
    //get the content of the file into a string
    while(!feof($tFileHandle)) 
     $tFileOutput = $tFileOutput . fgets($tFileHandle, 4096);
    fclose ($tFileHandle);
          
    $tFileHandle = fopen($tFile, "w");
    //write the new 8Bit string to the file
    fwrite($tFileHandle, imap_qprint($tFileOutput));
    fclose ($tFileHandle);
    ?>
    
    I tried to use this function. But it seems it requires php_zip.dll to be load.. i got the php errror like below.
