kmail: problem making sieve vacation messages work

[Hans-Peter Jansen]

Hi,

Ingo Klöckner from kmail fame suggested to reraise my issue here, since 
kolab is using the cyrus imap server, and hopefully somebody is using 
kmails vacation feature successfully here (even a negative result would 
help to decide to report this bug):

I'm trying to get the kmail sieve vacation messages going, but failed 
so far:

On the server, I use cyrus-imapd 2.3.8, and operating on the sieve scripts 
with sieveshell and with kmail "Manage Sieve scripts" (freely translated 
from german) works fine for my diverse accounts (the receive account 
settings are fine ("server supports sieve" and "use system and user account 
data" activated)), but selecting "Configure "Out of Office" Replies", 
activating it, and pressing Ok leads to:
Ungültige Adresse (URL): sieve://hp@imap.local.site:2000/?x-mech=PLAIN.
if using plaintext login, with TLS or without any encryption,
or
Ungültige Adresse (URL): sieve://hp@imap.local.site:2000/?x-mech=DIGEST-MD5.
if using digest-md5 login. 

I'm trying to use this feature since kmail 1.8 and cyrus imap 2.2.12 without 
success.

I already browsed through the source, but failed to being able to locate the 
issue :-(.. While the code looks promising, I (and my other users) would 
love to see it in action ;-)..

One thing, I don't like in the logic (even without seen it running..): To 
make this feature fully usable, it should provide a way to select the 
account, where the sieve script is activated. Now, it simply takes the 
first account with the sieve option enabled. 

Could someone give me hints on how to debug this problem further?

TIA,
  Pete
