In this bug there was a broken IMAP server and a misconfigured Horde 
setup.  Resolving = bogus.

I reinstalled Horde 3.1, just in case.  Then I found the problem:



$conf['auth']['params']['dsn'] = 
'{localhost:993/imap/ssl/novalidate-cert}INBOX';



But this should have been:



$conf['auth']['params']['dsn'] = '{localhost:993/imap/ssl/novalidate-cert}';



Thanks!

Are you using Horde < 3.1?  There appears to be an issue with BC 
between IMP 4.1 and the old way we used to handle the IMAP tree 
because this doesn't happen with Horde 3.1+.

FYI, I can see shared folders either way, but when I configura IMP for 
IMAP folder subscriptions, I can't see anything under INBOX., even if 
I make sure to subscribe to folders otherwise.  Without IMP using IMAP 
folder subscriptions, all the folders are in filesystem date order, 
and are named like INBOX.Stuff.Subscriptions.

I'm still having a problem like this.  If I try to use IMAP folder 
subscriptions, I can't see ANY folders (Courier-IMAP 4.1.0), and on 
the Folders page, I can't see any folders, nor create any.

I completely understand.  In the meantime, with your workaround, I can 
continue evaluating IMP 4.1 now that we can access all of our folders.
Hopefully there will be time to do the upgrade at some point this week 
(I have everything compiled and tested, I just need a lull to make the 
switch on the production IMAP server); I will make sure to report back 
in this incident whether or not the current version of Courier IMAP 
has the same problem.



Best regards (and thank you for the speedy responses),

Nick

At this point, I'm not sure what we can do to work around this.  If an 
IMAP server is advertising that it supports the 'CHILDREN' extension, 
and then doesn't provide children information when expected, it 
doesn't seem like there is too much we can do about this.



I will be interested to hear if upgrading the IMAP server solves this issue.

That change seemed to fix things; the nested folders show up now.  Great!



I am running a fairly old version of Courier IMAP (v3.0.5); I'll be 
upgrading that to v4.1.0 over this coming weekend, with any luck, and 
can test to see if the problem goes away with the upgrade.



Is there any further information I can provide, or do you consider 
this a non IMP bug and not worth the effort to work around?

It kind of looks like your IMAP server may be broken - the server is 
advertising it supports the CHILDREN extension, but none of your 
folders that have children appear to have the bitmask set indicating 
whether there are children or not - which means that 
imap_getmailboxes() is not returning correct information. Could you 
try replacing line 83 in imp/lib/IMAP/Tree.php with this:

                 $this->IMAPchildrenSupport(false);

Sure:

Can you add this line:

print_r($imptree);



to the end of imp/folders.php - go to that page - and then attach the 
output of that call to this ticket.

If you run the login test on imp/test.php, what's the result?

No; this is a side-by-side installation with our (production) IMP 
3.2.2.  I'm testing IMP 4.1 with an eye to replacing the production 
version.



Please let me know if there's any other information I could provide to 
help replicate the problem.

Did you upgrade from IMP 4.0.x?

Problem:



I can't see some nested folders within IMP 4.1 that do show up in 
native IMAP clients, like Thunderbird and Outlook.



Details:

My IMAP folder structure looks like this:



INBOX

INBOX.Drafts

INBOX.Mailing Lists

INBOX.Mailing Lists.Mailing List 1

INBOX.Mailing Lists.Mailing List 2

INBOX.Mailing Lists.Mailing List 3

INBOX.Sent



...



The INBOX.Mailing Lists folder contains no messages, just folders 
which contain messages from each mailing list I subscribe to.  When I 
expand the folder list in IMP 4.1, Mailing Lists is empty, and does 
not have any children folders.  When I use a native IMAP client, I can 
see each mailing list folder and read messages in it.



Software versions:



IMP v4.1

Horde v3.1

PHP v4.3.4

Apache v2.0.48

Courier-IMAP 3.0.5
