ps: regarding this mailing list:
Why do the headers of the mailing-list-mails not contain a "List-Id" ? I use that for server-based filtering with other lists. Very handy ...
I don't know. Does mailman support "List-Id"? RFC-2369 headers are enabled, so I guess that will include List-Id.
I don't see/find it (even in your latest mail now). But I can also filter for "Organization: IPFire.org", no problem.
Thanks, Stefan
