Spam Rank Alert is a simple bash script which uses an IP you specify, to
look up the senderbase score on www.senderbase.org (owned and operated by Cisco),
and alerts an email recipient if that score has reached a predetermined threshold.

For more information on the senderbase score, please read senderbase.org,
http://www.senderbase.org/help/magnitude
http://www.senderbase.org/help/simple_search

A single infected computer on a small network, (less then 50 workstations)
can cause the senderbase score to jump to a magnitude of 2.0 or even higher.
This increase in spam can have a severe impact on your domain to send emails.
Multiple blacklist will start including your domain and/or IP and causing your
emails to start bouncing. This is never a good thing if your business relies on
email for communications. This script is not a preventative solution, but rather
a tool to warn of potential threats/issues that are happening within your domain.

This script will monitor the senderbase score, and send alerts when the threshold
has been reached. Once the threshold has been reached, Spam Rank Alert will send
alerts if the score is consistantly increasing and/or decreasing.

The best way to use this script is to place it into a cronjob running every 15 minutes.
Senderbase.org is near realtime, so usually within 15-30 minutes of a computer being infected,
the senderbase.org score increases dramatically, which depending on the threshold set,
will trip the alerts.
