Rule File Updates
As new spam is written and released onto the public, and as spammers jump from routing domain to routing domain to cover their tracks, Trend monitors and collects telltale blocking information and incorporates it into new Rule and Import files. The Rule file is used by the spam filter and contains numerous predefined anti-spam rule-sets. Imported files are used by the content filter and can augment existing policies.
Clearly, it is very important to keep these files up to date. New Rule and Import files are typically published monthly by Trend, and you should not wait much longer than that to update the file.
Updates are available free to registered Trend eManager customers. The updates can be scheduled to be automatically downloades over the Internet, or obtained "on demand" (make the Rule File Update page active and click Update Rule File).
The rule file is kept in the following directory:
Opt/trend/Plug-Ins/EM/spamrule
Rule-file names are as follows: Trend$RF.1, where .1 represents the rule file version. When multiple rule files exist in the directory, only the one with the most recent extension (the highest number) is read.
