Folder name space and the '&' character

Hi,
  lets try this again.

I'm having problems with folders containg the '&' character (which is causing our Webmail users some grief).

I crated two files named 'b &- d' and 'C & D' and then did a:

      Folder root = store.getDefaultFolder().getFolder("mail/amp");
      Folder[] folders = root.list("%");
      for (int i = 0; i < folders.length; i++) {
        try {
          System.err.println(folders[i].getFullName());
          if (!folders[i].exists()) {
            System.err.println(" (doesn't exist?)");
          }
          else {
            folders[i].open(Folder.READ_ONLY);
            folders[i].close(false);
          }
        } catch (javax.mail.MessagingException me) {
          System.err.println(me);
        }

with the following output:

DEBUG: setDebug: JavaMail version 1.3.1 * OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS AUTH=LOGIN] localhost IMAP4rev1 2003.338 at Thu, 24 Jul 2003 12:34:16 -0700 (PDT) A0 CAPABILITY * CAPABILITY IMAP4REV1 IDLE NAMESPACE MAILBOX-REFERRALS BINARY UNSELECT SCAN SORT THREAD=REFERENCES THREAD=ORDEREDSUBJECT MULTIAPPEND LOGIN-REFERRALS STARTTLS AUTH=LOGIN A0 OK CAPABILITY completed A1 OK [CAPABILITY IMAP4REV1 IDLE NAMESPACE MAILBOX-REFERRALS BINARY UNSELECT SCAN SORT THREAD=REFERENCES THREAD=ORDEREDSUBJECT MULTIAPPEND] User xxx authenticated A2 LIST "" mail/amp * LIST (\NoSelect) "/" mail/amp A2 OK LIST completed A3 LIST "" "mail/amp/%" * LIST (\NoSelect) "/" mail/amp/ * LIST (\NoInferiors \UnMarked) "/" "mail/amp/b &- d" * LIST (\NoInferiors \UnMarked) "/" "mail/amp/C & D" A3 OK LIST completed mail/amp/b & d A4 LIST "" "mail/amp/b &- d" * LIST (\NoInferiors \UnMarked) "/" "mail/amp/b &- d" A4 OK LIST completed DEBUG: connection available -- size: 1 A5 EXAMINE "mail/amp/b &- d" * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1059075256] UID validity status * OK [UIDNEXT 1] Predicted next UID * FLAGS (\Answered \Flagged \Deleted \Draft \Seen) * OK [PERMANENTFLAGS ()] Permanent flags A5 OK [READ-ONLY] EXAMINE completed A6 CLOSE A6 OK CLOSE completed DEBUG: added an Authenticated connection -- size: 1

mail/amp/C
A7 LIST "" "mail/amp/C "
A7 OK LIST completed
 (doesn't exist?)

As you can see, the folder name of 'b &- d' comes out as 'b & d' and of 'C & D' comes 
out as 'C '.
This makes in difficult, if not impossible to access the folders.

I also tried this with pine (no problems), mozilla mail (folders appears as 'b & e' 
and 'C D'),
and KMail (folders appears as 'b & e' and 'C D', but I can' access the messages in
the folders)

And if I read RFC3501, section 5.1.3, correctly, isn't the imap server supposed to 
escape the
'&' properly since this is the signal to the client that the string is BASE64 encoded?

So what is going on here, and how do I fix/get around this problem.

Thanks

    George
