cyrdeliver, exim on sarge - deliver spam to folder

["Mihály Litzler" <mlitzler@gmail.com>]

Hi!

I would like to deliver spam mails into a different folder instead of INBOX by default to all of my users. Simply do a sorting on the header Spam-Flag...

I did Google, rtfm, etc. I did my best, however I couldn't solve this problem:


Exim routers:

cyrus_vdom_spam:
    debug_print = "R: cyrus vdom spam for $local_part@$domain"
    driver = accept
    domains = +cyrus_domains
    transport = cyrus_spam
    condition = ${if match {$message_headers:}{X-Spam-Flag: YES} }

cyrus_vdom:
    driver = accept
    domains = +cyrus_domains
    transport = cyrus_inbox
    no_more

Exim transport:

cyrus_inbox:
    driver =lmtp
    user = cyrus
    socket = /var/run/cyrus/socket/lmtp

cyrus_spam:
    driver = lmtp
    command = "/usr/sbin/cyrdeliver -l"
    user = cyrus


1. 
If I use cyrdeliver -l in cyrus_spam that way, the -m Spam flag make no sense. 

2. 
If I use something like this:

cyrus_spam:
    driver = pipe
    command = "/usr/sbin/cyrdeliver -m ${local_part}.Spam -- ${local_part}"
    user = cyrus

I got a "message contains invalid header" error.

3.
I also tried to do some global sieve filter, but as I know it's unsupported.

Actually, there are only virtual users exists, everything comes from LDAP.

Would you so kind to write a working exim, imapd etc. config for this. However everything is alright.., exim delivers mail, I can use Cyrus in a Thunderbird correctly, just this problem with delivering to especially the 'Spam' folder ...

Thanks in advance!
