I just tested sending a message and got:

"Your mail to 'grass-web' with the subject
    test message from unsubscribed address
Is being held until the list moderator can review it for approval.
The reason it is being held:
    Post by non-member to a members-only list
Either the message will get posted to the list, or you will receive
notification of the moderator's decision.  If you would like to cancel
this posting, please visit the following URL:   ..."


strange.

I don't think so, they keep coming, even new ones in the last 2 days.

AFAIK Markus is the one shouldering the approval work here, so I would
leave the decision up to him.

What does "poorly configured" email system mean?
(e.g. I often spoof my own from address so I can post using a local SMTP
server not yahoo's [university firewall issues, local client,
fetchyahoo.pl cron job -> local mbox, ...])
