How does the IP Reputation Filter work

The IP Reputation filter in Xeams looks checks the number of junk messages that have been received in the past from a particular IP subnet. The default behaviour is to check for last 2 days of data and if more than 7 junk messages. This means if more than 7 junk messages are received from an IP subnet, this rule will assign a score to future incoming emails.

Changing default values

There are two configurable parameters for this rule:
  1. Maximum number of days to go back
  2. Minimum number of junk emails received
You can change these settings by following the steps below.
  • Locate server.properties file in $INSTALL_DIR\config folder. Create a new text file if this file is not found on your system.
  • Enter the following lines:

    min.messages.b4.spam.ipreputation=10
    num.days.cache.4.ipreputation=5
  • Save the file
  • Restart Xeams
The above example will change the number of days to 5 and minimum email count to 10.
