Filter incoming mail from lists with mailfilter

[Toby]

Hi,

I got problems with my .mailfilter (maildrop) config. The sorting of 
incoming emails from different Ubuntu mailing lists fails.

Here is a snippet:

# Debian mailing lists
if (/^X-Mailing-List: <debian-announce at lists.debian.org>/)
         to "$HOME/Maildir/.Linux.Debian.Announce"

if (/^X-Mailing-List: <debian-news at lists.debian.org>/)
         to "$HOME/Maildir/.Linux.Debian.News"

if (/^X-Mailing-List: <debian-user at lists.debian.org>/)
         to "$HOME/Maildir/.Linux.Debian.User"


# Ubuntu mailing lists
if (/^X-BeenThere: ubuntu-server at lists.ubuntu.com>/)
         to "$HOME/Maildir/.Linux.Ubuntu.Server"

if (/^X-BeenThere: ubuntu-users at lists.ubuntu.com>/)
         to "$HOME/Maildir/.Linux.Ubuntu.User"


I've had the Debian entry's for years and they still work. I recently 
signed up for the Ubuntu lists and it fails. All emails from Ubuntu 
lists ends up i the standard Inbox.

The "X-Mailing-List" header is missing from the Ubuntu lists and it 
seems "X-BeenThere" does not work. Anyone got a hint for me?

Thanks!
