Every time you create or update a mail rule, or change the order of mail rules, FirstClass compiles the rules for that container. This is done to locate any errors in the rules, such as a missing folder name. The results of the compile are recorded in a rules log that FirstClass places in the container's Rules & Resources folder.
The cost is a general indicator of how much impact your rules processing will have on the server. The higher the number, the more server resources you are using. A cost up to 25 has little impact on the server. Above 50 has a high impact, and may result in slower response times. Each compile adds to this log. If you want FirstClass to start a new log, delete the old one.  CautionBe sure to correct any errors reported by the log before your new or updated rule runs. | ||
