Description:
------------
If I run an imap_fetchstructure() on POP3 on a multipart/mixed message with a file attachment I get

object(stdClass)(12) {
  ["type"]=>
  int(1)
  ["encoding"]=>
  int(0)
  ["ifsubtype"]=>
  int(1)
  ["subtype"]=>
  string(5) "MIXED"
  ["ifdescription"]=>

  int(337991)

  ["parameters"]=>
  array(1) {
    [0]=>
    object(stdClass)(2) {
      ["attribute"]=>
      string(8) "BOUNDARY"
      ["value"]=>
      string(41) "----=_NextPart_000_004B_01C4B881.82B4DE80"
    }
  }
  ["parts"]=>
  array(2) {
    [0]=>
    object(stdClass)(12) {
      ["type"]=>
      int(0)
      ["encoding"]=>
      int(0)
      ["ifsubtype"]=>
      int(1)
      ["subtype"]=>
      string(5) "PLAIN"
      ["ifdescription"]=>

      array(1) {
        [0]=>
        object(stdClass)(2) {
          ["attribute"]=>
          string(7) "CHARSET"
          ["value"]=>
          string(10) "iso-8859-1"
        }
      }
    }
    [1]=>
    object(stdClass)(13) {
      ["type"]=>
      int(5)
      ["encoding"]=>
      int(3)
      ["ifsubtype"]=>
      int(1)
      ["subtype"]=>
      string(4) "JPEG"
      ["ifdescription"]=>
      int(0)
      ["ifid"]=>
      int(0)
      ["bytes"]=>
      int(337122)
      ["ifdisposition"]=>
      int(1)
      ["disposition"]=>
      string(10) "ATTACHMENT"
      ["ifdparameters"]=>
      int(1)
      ["dparameters"]=>
      array(1) {
        [0]=>
        object(stdClass)(2) {
          ["attribute"]=>
          string(8) "FILENAME"
          ["value"]=>
          string(14) "email left.jpg"
        }
      }
      ["ifparameters"]=>
      int(1)
      ["parameters"]=>
      array(1) {
        [0]=>
        object(stdClass)(2) {
          ["attribute"]=>
          string(4) "NAME"
          ["value"]=>
          string(14) "email left.jpg"
        }
      }
    }
  }
}

If I run exactly the same code under an IMAP4 extension I get

object(stdClass)(11) {
  ["type"]=>
  int(1)
  ["encoding"]=>
  int(0)
  ["ifsubtype"]=>
  int(1)
  ["subtype"]=>
  string(5) "MIXED"
  ["ifdescription"]=>
  int(0)
  ["ifid"]=>
  int(0)
  ["ifdisposition"]=>
  int(0)
  ["ifdparameters"]=>
  int(0)
  ["ifparameters"]=>
  int(0)
  ["parameters"]=>
  object(stdClass)(0) {
  }
  ["parts"]=>
  array(1) {
    [0]=>
    object(stdClass)(12) {
      ["type"]=>
      int(0)
      ["encoding"]=>
      int(0)
      ["ifsubtype"]=>
      int(1)
      ["subtype"]=>
      string(5) "PLAIN"
      ["ifdescription"]=>
      int(0)
      ["ifid"]=>
      int(0)
      ["lines"]=>
      int(19)
      ["bytes"]=>
      int(441)
      ["ifdisposition"]=>
      int(0)
      ["ifdparameters"]=>
      int(0)
      ["ifparameters"]=>
      int(1)
      ["parameters"]=>
      array(1) {
        [0]=>
        object(stdClass)(2) {
          ["attribute"]=>
          string(7) "charset"
          ["value"]=>
          string(10) "iso-8859-1"
        }
      }
    }
  }
}

It doesn't seem to be c-client related as it seems to work connecting to other mail servers from the same web server, however connecting to this particular exim server produces this problem.

I am retrieving message UID's and not sequence IDs and the actual body of the message is displayed correctly, just the attachment missing.

The email source is as follows (headers changed to protect details and image condensed on purpose for size but I have kept the exact structure and number of carriage returns)

---------------
$structure = imap_fetchstructure($mailbox, $msgid, FT_UID);

Expected result:
----------------
Retrieves body of message and one image file attachment in the structure

Actual result:
--------------
Retrieves body of message and no image files attachments in the structure
