[imapfilter] List-Id not filtered

[Mihamina Rakotomandimby <mihamina@...>]

Hi,

I have a problem with *one* pattern.

For the Mandriva Cooker mailing list, I get these headers:

Here is how I try to match the "List-Id" header:

On the only "cooker" case, messages are not matched.
I always see the [cooker] email in my INBOX: they are not moved to the 
mandriva folder as I set it.

I run out of idea about the problem cause.
Would you help?

Thank you.
