Subject: [sup-talk] [PATCH] Add list-id as a new property of messages
Message-ID: <1208985725-sup-6028@elly>

Hi there,

I propose to add a "list_id" property to messages, just like
list_subscribe, list_unsubscribe and list_address.

I am using list_address.email to automatically generate labels for
messages that are coming from mailing lists (that field uses the value
of the List-Post header of the raw message). It seems that some
mailing lists are not including that header though. In those lists
where I do not see List-Post, I have found that List-Id is still
present. Therefore I propose to add that header to the message class
for filtering purposes.

The change is minimal, and as far as I have found out, it does not
affect any other part of Sup (like for instance the index of
messages). I am attaching the patch below.

Cheers,
Israel
