procmail rule to filter debian-user

[Bijan Soleymani <bijan@psq.com>]

Hey everyone,

I need a rule to filter debian-user into a seperate maildir. I know 
there's the header:
X-Maling-List: <debian-user...

so I tried:
* ^X-Mailing-List: <debian-user.*
/home/bijan/Maildir/.lists.debian/

and several variations, but none of them worked.

Thank in advance,
Bijan
