[Dovecot] Filtering with Public Namespaces and Sieve Plugin

[Thomas Leuxner]

Hi,

after upgrading to Dovecot 1.2x including the rewritten Sieve plugin replacing 'cmusieve', messages which have formerly been filed to a "Public/Mailing-List" maildir are no longer filtered correctly. The sieve script itself is included in the user's personal-script. The messages are dropped to the INBOX rather than the "Public Namespace Maildir". Log's don't give a hint (at least to me). The documentation says the personal script should automatically fetch the include, and compile it in the users home...

Personal ".dovecot.sieve" script:
------------------------------
require ["include","copy","fileinto","vacation"];
include :global "global.sieve";

Global script "global.sieve" excerpt:
------------------------------------
require ["copy","fileinto"];
#Newsletters / Mailinglists

if allof (address :is ["To","CC"] "dovecot at dovecot.org",
        header :contains "List-Id" "dovecot.dovecot.org")
        {
        fileinto "Public/Mailing-Lists.Dovecot";
        }
        elsif allof (address :is "To" "dovecot-news at dovecot.org",
        header :contains "List-Id" "dovecot-news.dovecot.org")
        {
        fileinto :copy "Public/Newsletters.Dovecot";
        }

Thanks
Thomas
