Messages for group@php.net are in pending

Hello,
I have a request destined to the php "group", relevant of the
authorization to use "PHP" root in a project name. This must be done by
sending a mail to group_at_php.net but this adresse seems to be out of
order.

Hi. This is the qmail-send program at php.net.
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.

<group_at_pair2.php.net>:
j-c.gibier_at_wanadoo.fr is in pending
I'm not going to try again; this message has been in the queue too long.

Is there another way to pass my demand to the persons supposed to deliver
prior written permission ?
Thanks for your advices.

regards
JCG
