that was because they were replies and were addressed to the person who asked
the questions, so they had his address in "To:", and only in
"Cc:" they had dovecot at dovecot.org.

I consider it a better idea to filter mailing list messages by their
List-ID header.

I agree with Markus.  It's what I do.  This works well:

if header :regex "list-id" "solr-user.lucene.apache.org"
{
         fileinto "asf.solr-user";
         stop;
}

I do not know if List-ID is common to all mailing list software, but 
even if it's not, there should be something available in the message 
headers that you can use.

Thanks,
