Closed Feature: Problem with IDLE support [2382]

Hi,
I am working on a vb.net program that should show the newest e-mails from my IMAP account. I want to implment this with the IDLE support.

In principal it works perfect. However, the server of my provider df.eu sends from time to time, but the latest after 120 seconds the message "OK Still there".

IDLE stopps after this message.

What can I do? Logfile is enclosed.

Thanks,
Arnulf
