Hi. This is the qmail-send program at lists.suse.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<suse-linux-ja@xxxxxxxxxx>:
ezmlm-reject: fatal: message already has a Mailing-List header (maybe I should be a sublist) (#5.7.2)

という内容ですが具体的に何が悪いのかよくわからないのです。
教えて君で大変申し訳ないのですが、SUSEのメーリングリストの管理者にも
問い合わせをしているのですが、なかなか返事が届かずここのメーリング
リストにアップしました。

どうぞ宜しくお願いします。
