dovecot - Oct 2010 - After Upgrade to Dovecot 2.0.5 SSL problems

Hi,
 
 I've upgraded my Dovecot from 1.2 to 2.0.5. Everything is working fine on
my Gentoo, also login with imaps and pop3s.
 
 But:
 
 I have in my config autocreate folders for new users. After creating a   new
user (with PostfixAdmin) I see in my logfile with SSL enabled this:
?
imap-login: Warning: SSL alert: where=0x4004, ret=560: fatal unknown CA
[127.0.0.1]
?
With SSL-disable, autocreation folders for new users is no problem.
 
 I've searched a fiew days for a solution, but I did not find anything. 
Also dovecot-page what describes running SSL does not help me.
 
 Here are the relevant config-sniplets:
?
plugin {
? autocreate = Trash
? autocreate2 = Sent
? autocreate3 = Junk
? autocreate4 = Drafts
? autosubscribe = Trash
? autosubscribe2 = Sent
? autosubscribe3 = Junk
? autosubscribe4 = Drafts
}

service imap-login {
? inet_listener imap {
??? address = *
??? port = 143
? }
? inet_listener imaps {
??? address = *
??? port = 993
? }
}

ssl = yes
ssl = yes
ssl_cert =

So imaps/pop3s works fine for most users?

I think this means the client doesn't think the server's certificate is
valid (it doesn't have your CA) so it disconnects.

I don't think this has anything to do with folder autocreation.
