Install ASSP Script, Tune Plesk Mail Server

We have a Linux server with Plesk 8.3 admin panel. Some unexpected traffic has been coming through the server we wish to stop. So, we need the ASSP script installed and the server's mail sending function restored. The ASSP install should be tuned to stop all but permitted traffic. After submitting a bid, please contact us at webmaster at crownseo dot com to let us know as GAF often does not provide timely notification of bids.
