When I check the "INBOX" and select "Create folder", the popup appears. I enter "subfolder" as folder name. The creation of the new folder fails as it tries to create the folder "/subfolder". When I do the same thing without checking "INBOX", so it defaults to INBOX, my subfolder INBOX/subfolder gets created fine. Anyone else seeing this? Thomas Tue, 03 Jun 2008 16:30:43 +0000 https://bugs.horde.org/ticket/6827#t45883 I found the source of the issue. IMP tried to create folders below "INBOX" like this: "INBOX//new_folder". The error occurs in imp/lib/IMAP/Tree.php::createMailboxName($parent, $new). Here's a dump of the $ns_info structure: Array ( [name] => INBOX/ [delimiter] => / [type] => personal [hidden] => ) $parent is set to "INBOX", $new is "new_folder". Here's the code that computes the folder "base": $mbox = $ns_info['name']; --> mbox is "INBOX/" $mbox .= rtrim(substr_replace($parent, '', 0, strlen($ns_info['name'])), $ns_info['delimiter']) . $ns_info['delimiter']; substr_replace($parent, '', 0, strlen($ns_info['name'])) will lead to an empty string. rtim() is a noop in this case. Then we append the delimiter, so this results in "INBOX//". I've developed a fix, though I don't know if "name -> INBOX/" is right in the first place.

We just needed to do the rtrim on the whole string, not just the part we were adding. So slightly modified your patch to do this and committed to IMP 4.2.1.
