We have started work to implement the following:

*  The delay on the feed from our news server to the gateway has been
increased from one hour to three hours. This will delay posts, but
since most spams are cancelled fairly quickly it will stop most spams
before they get to the gateway and are distributed to the mailing lists.

*   We will implement a check on incoming articles. If the same article
appears more than ten times in a two hour period we will consider it a
spam and will not feed it to the gateway.
