rejected posts to alpine-info

[Pierre Frenkiel <p.frenkiel@laposte.net>]

when I try to send a mail to the alpine-info list, I get the following error
message:

   You are not allowed to post to this mailing list, and your message has
   been automatically rejected.  If you think that your messages are
   being rejected in error, contact the mailing list owner at
   alpine-info-owner@mailman13.u.washington.edu.

Of course, my mails to alpine-info-owner are also rejected!!
any idea?
I hope that my post to this list will have a better treatment.

best regards,
