IMAP: Umlaut problem in folder names in 8.0.2

Hi,

can someone confirm the problem that I see with Umlauts in folders when accessing the mail file (mail8.ntf, 8.0.2) via IMAP?

Background:

I have a few folders with German names like

“Jörg” or “Günter”. Whenever I access these folders the 8.0.2 (on all platforms [Solaris, Windows 2003]) the IMAP server throws an error.

Thanks for any hints,

Uwe
