How does the IP Reputation Filter Work
The IP Reputation filter in Xeams checks the number of junk messages that have been received in the past from a particular IP subnet.
The default behavior is to check for last 2 days of data and if the data has 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:
- Maximum number of days to go back
- Minimum number of junk emails received
You can change these settings by following the steps below.
The above example will change the number of days to 5 and a minimum email count to 10.
Bypassing certain IP addresses
Create a file called
IPRepExceptions.dat
in
$INSTALL_DIR\config containing a list of IP address that you need to skip. The file must
have one IP address per line.
Create a file called
SkippedDomainsForIPRepExceptions.dat
in
$INSTALL_DIR\config containing a list of domain names. Xeams will do a reverse
lookup for the IP address and if it the top-level domain matches the host name in the file, no score will be assigned.

This would be a useful feature to add to the UI and master/slave synchronisation.
