[horde] Problems with Filter rules after login

[info@web-front.de]

Hello,

my System: Horde 3.1.1. Turba 2, IMP4, IngoH3 1.1

My first problem is:

6 filter rules are active 
and the filtersettings are:
Filterregeln immer anwenden, wenn INBOX angezeigt wird?

The Login to Webmail are ok, because i can't open the Inbox-Folder.
The other Folders can i open.


The second problem:

Many users have over 2000 Emails in thier Inbox. Have Ingo e.g. the Filter problems with so much mails?


How can i fix it?

Regards
Thomas
