Andy,

I did some testing with recordio (I figured out how to use it!).

I moved all my squirrelmail preference settings out of the way, and all the
bincimap files our of my Maildir, i.e. started clean with no folders
subscribed. I found I could log in OK.

I then subscribed to all my folders, logged out and logged back in again.

The resulting log file (using recordio, remember) contains one of these for
every folder I am subscribed to:

2003-08-04 20:47:57.746207500 7156 < A033 LIST "" "INBOX/Lists/getmail"^M

Digging in the squirrelmail code, the file imap_mailbox.php contains the
following code starting at line 572:

/*
* The LSUB response doesn't provide us information about \Noselect
* mail boxes. The LIST response does, that's why we need to do a LIST
* call to retrieve the flags for the mailbox
* Note: according RFC2060 an imap server may provide \NoSelect flags in the
LSUB response.
* in other words, we cannot rely on it.
*/
$sorted_list_ary = array();
for ($i=0; $i < count($sorted_lsub_ary); $i++) {
  if (substr($sorted_lsub_ary[$i], -1) == $delimiter) {
    $mbx = substr($sorted_lsub_ary[$i], 0, strlen($sorted_ls
ub_ary[$i])-1);
  }
  else {
    $mbx = $sorted_lsub_ary[$i];
  }
  $mbx = stripslashes($mbx);
  $read = sqimap_run_command ($imap_stream, 'LIST "" ' .
sqimap_encode_mailbox_name($mbx),
                              true, $response, $message);

So, squirrelmail is doing a "LIST" for every folder I'm subscribed to.
That's 198 folders!

Next step is to find why it's doing this with bincimpa but worked OK with
courier-imap.

Any ideas?
