Spam Blacklist One problem that could be detected by monitoring blacklist servers would be when one of your end users receives a Trojan program which uses the corporate mail servers to send SPAM or copies of itself on to other email systems.  As a result of the mass mailing caused by the virus, your corporate mail server becomes blacklisted.  Other business partners begin to block your mail because of your blacklist status.  You need to know that you have been blacklisted so you can track down the reason why, fix the problem, and then send a request to the blacklist administrator that your address range be removed from the blacklist.
