Horde - Inbox - empty

[keff]

Hi,

one of my clients store all mails on server and has >6000 messages. Horde stops shows all the messages in INBOX folder. Only the new e-mail shows in Wirtual Inbox. When he try to view INBOX folder, he shows empty box.

How to fix it?

Memory limit in php.ini has only 8M, I've set it to 16M and it works fine.
