[Dovecot] Error in IMAP command GETACL: Unknown command..

Hi all, I have just installed dovecot on my Fedora Core 2 box. I would like to use it only for reading archived email from within my Mozilla 1.7.3.

I syminked my old opera-files (*.mbs whoch seems to be same as mbox) into ~/mail. Seems to work fine, mostly I can open the mailfiles - sometimes it hangs with the following error:

The current command did not succeed. The mailserver responded:
Error in IMAP command GETACL: Unknown command..

And then: The current command did not succeed. The mailserver responded: Error in IMAP command MYRIGHTS: Unknown command..

ALthough I searched in Google and in the Wiki on dovecot, I did not find any hint - am I the first with this problem?

TIA Ingo.
