Hi all several members have been complaining about their inability to post messages to blacksheep. With the assistance of Chris 2E0ILY and his cooperative hosting site technical help desk, we have confirmed that his "lock-out" is due to exceeding the spam score on a message and being flagged as a spammer. It would seem that this state does not expire nor are subsequent messages even tested. You are still able to receive the distribution but not post.

As far as I can see this state can only be manually reset by the (non-existant) admin. The only solution seems to be to re-subscribe with a different email address. This does mean you will get two copies of the distribution because being flagged you may not get an unsubscribe message to the system either.

The spam scoring utility uses statistics to assess the probability a message is spam, see...

the result is it is likely to make mistakes occasionally. The system uses path, domain, route (Laurence KL7K could not get in from China) and message content to derive a score.....so beware a jokey comment might get you banned :-))

I am sorry we cannot help further on this problem.
