Overview The power and flexibility of Denes has lent greatly to it immediate success as a tool for EIMS administrators around the world. With all of this flexibility though comes a great number of options that administrators can choose from for their EIMS installations. And, with all of the power of Denes, it important to understand how different rules within Denes may impact the functionality of SMTP services within EIMS. Cool Rules allow you to see real rules that make Denes function in real world production environments. Each rule presented here has a short description of what the rule does specifically. And, each rule is presented with a list of any shortcomings that may exist by implementing such a rule in a particular installation of EIMS. Rules are categorized into three sections. The categorization is based on the skill and knowledge level required to understand what the rules do and how best to implement them in a particular EIMS installation. As a learning tool for using Denes, it is best to understand all of the rules and options in any single category before moving on the working with the rules in any successive category. Submit Rule The best way to see this list of rules grow is to submit your own rules that you have found to be useful with Denes. The following form allows you to do that. Remember, most rules come in pairs to include the error log entry rule. Please do include your error log entry line, as appropriate, with any rules you submit. And, do know, any domain specific parameters in submitted rules will be substituted so posted rules are as generic as possible. * Full Name: Company: * Email: * Phone: Denes version: v1.0.x v1.1.x Preferred Rule Name: * The Cool Rule(s): * Short Description: * Required items to submit rule.

Basic Rules The basic rules are simple and useful examples of implementing rules in Denes in your EIMS installation. It provides for simple rule logic with few substitutions or options. Basic RBLs are a good example of what would be consider a basic rule for Denes. Open Relay Database - DNSBL Reactive Autonomous Blackhole List - DNSBL More coming soon... Intermediate Rules Intermediate rules provide a little more complexity in the logic or operation of the rule within Denes. This does not mean that they require any more processing within Denes, necessarily. Though, with substitutions more commonly used, alternative values within the SMTP transaction being used in the NS lookups and comparisons, and use of more of the operator and string values for greater control, these rules would all be considered more complex than any of the simple rules. A better understanding of the SMTP transaction, NS lookups, and commonly used practices online involving email all contribute to making these rules of intermediate complexity. Bogus MAIL FROM - Domain in MAIL FROM not for Email Dynamic IP v1.0.0 - Block dynamic IP address, including dialups, DSL, and cable IP addresses More coming soon... Advanced Rules The advanced rules are by far where all of the power of Denes can be maximized. These rules involve multiple substituion usages, custom NS entries for creating local black and white lists, and taking advantage of common usage techniques to glean additional information from NS lookups for use in rules with Denes. Mastering the davanced rules within Denes allows you to master the techniques to make your SMTP server as efficient and powerful as possible. More coming soon...
