ERROR: SUBSCRIBE "INBOX.Sent": Mailbox nonexitent

I'm running SquirrelMail 1.4.3a. My "folders"? pane contains:

<snip>
ERROR:

ERROR : Could not complete request.
Query: SUBSCRIBE "INBOX.Sent"
Reason Given: Subscribe: Mailbox does not exist
</snip>

It's true, "INBOX.Sent" doesn't exist - but "$auto_create_special = true" in config.php. Why doesn't SquirrelMail create "INBOX.Sent"?

"INBOX.Sent" doesn't exist, but "INBOX.Sent.some-sub-mailbox" does. Could this be SquirrelMail's confusion? I haven't tried removing "INBOX.Sent.some-sub-mailbox" yet. I'm not real familiar with SquirrelMail - I'm not sure what other debug information I should provide.

Suggestions of what to try or what to check much appreciated!

Thanks,

Jack

These folders are IMAP folders. So what sort of IMAP server are you using? How sure are you about the IMAP install?
Courier I believe is still the preffered IMAP followed by UW for ease of install since it comes installed with RedHat and some other distros.

Good luck

Thanks,

I double checked the IMAP server to be sure; I'm responsible for this server, so I'm pretty sure it's tickety-boo. It's running Cyrus IMAPd 2.1.16.

I tried removing all "INBOX.Sent.*" mailboxes; this made a difference: Now the "folders" pane contains:

<snip>
ERROR:

ERROR : Could not complete request.
Query: SUBSCRIBE "INBOX.Trash"
Reason Given: Subscribe: Mailbox does not exist
</snip>

("INBOX.Trash" doesn't exist, though "INBOX.Trash.<submailbox>" does.)

So I think SquirrelMail's auto_create_special feature is incorrectly determining that special mailboxes exist in the case that they don't, but they are prefixes to other mailboxes.

I haven't looked at SquirrelMail's source code yet.

I had a gander at the source. I think this problem I'm having arises from sqimap_mailbox_exists:

<snip>
function sqimap_mailbox_exists ($imap_stream, $mailbox) {
if (!isset($mailbox) || empty($mailbox)) {
return false;
}
$mbx = sqimap_run_command($imap_stream, "LIST \"\" \"$mailbox\"",
true, $response, $message);
return isset($mbx[0]);
}
</snip>

Using the cyradm IMAP shell, listmailbox INBOX.Blah "" (where no mailboxes INBOX.Blah* exist) returns an empty list, so isset($mbx[0]) should correctly return false.

However, listmailbox INBOX.Trash "" (where INBOX.Trash doesn't exist, but INBOX.Trash.<submailbox> does) returns:

INBOX.Trash (\NonExistent \Noselect \HasChildren)

So isset should return true; sqimap_mailbox_exists should return true though the mailbox is "NonExistent".

I don't know if this is a problem with SquirrelMail and standards compliant IMAP servers, or just Cyrus.
