Three New Problems with Webmail

There are three new problems with web email. They did not exist before, and they're present in both Horde, Roundcube and SquirrelMail:
* Unread mail count not appearing in webpage title / tab.
* “Clear Trash on logout” setting not working.
* Can not deleted unused special folders.

To reproduce:

1. Login to any of the three webmail clients.
2. Create email and mail to self.
EXPECTED RESULT: Webpage title tab reflects the unread count "(1) Webmail – Main"
ACTUAL RESULT: Webpage title remains unchanged.
3. Verify: Settings -> Server Settings -> “Clear Trash on logout” is checked.
4. Delete test email from step 3.
RESULT: email moved to "Trash" directory.
5. Logout.
6. Login per step 1.
EXPECTED RESULT: Draft email deleted.
ACTUAL RESULT: Draft email remains in "Trash" directory.
7. Goto: Settings -> Special Folders.
8. Special folders "Archive" and "Junk" are not used.
9. Goto: Settings -> Folder.
10. Delete folders "Archive" and "Junk".
RESULT: Folders are deleted.
11. Goto: Mail link.
12. Goto: Settings -> Folder.
EXPECTED RESULT: "Archive" and "Junk" folders remain deleted.
ACTUAL RESULT: "Archive" and "Junk" folders are recreated.

I tried emailing customer support but they were evasive and unhelpful. Not a good reflection on inmotionhosting.
