kmail 1.10 (kde 4.1) cant talk tls to my imap server

[Marc Schröder <xen@gibmir.net>]

hi,

i installed yesterday kde 4.1 on my debian lenny box. all things seems 
fine so far. good work. but, i cant use kmail for email reading. my 
cyrus imap server is configured to talk tls with certificate base 
authentication. that was no problem with kmail from kde 3.5.9. is there 
any config i forgot? i found a bug report from suse/novel user, but 
without a solution. (https://bugzilla.novell.com/show_bug.cgi?id=383402)
is that a bug or have i run any kde service (kssl)? thats really a show 
stopper for me. please help.

btw. tls via smtp is no problem

thx marc
