To use ePrism spam controls to their fullest extent, consider the following:
Identify which systems will be "trusted," i.e., if systems are on different internal networks, ePrism must know they can be trusted. Also note any external systems that may need to relay via ePrism.
Plan to enable RBL lists, DCC and STA. These tools require little configuration and maintenance once they are setup and will provide your main defense against spam. Note: You can selectively enable or disable any one of these tools. However, if you plan to use STA, you almost certainly should use DCC as well.
Learn how to whitelist or blacklist sources and types of mail. This is essential for obtaining a good result with few false positives. Use whitelists to exempt mail that is wrongly classified as bulk such as valid mailing lists. Use blacklists to catch any spam that eludes the other defenses.
Educate your local user community on these tools. Users need to know why messages are being classified as they are and how to provide feedback on how well the system is performing. Appropriate feedback can help identify the thresholds in DCC and STA, as well as provide input for building the whitelists and blacklists.
