The IP Blocker service rejects messages originating from IP
addresses blacklisted by SophosLabs. Enabling
this option can improve performance by blocking spam before it reaches more complex
tests in the policy.
Note: Whether you choose to block IP addresses by enabling MTA-level IP blocking or by using
the PureMessage policy, PureMessage requires that the IP Blocker Service be enabled.
The IP Blocker Service: Status page shows the following information
in the Blocker Status table:
- Status: Whether the service is running.
- Summary: The PureMessage package name
that provides this service and the port used to access it.
- Config: Whether the configuration of this service is current.
- Port: The port number used to communicate with this service.
- PID: The Unix/Linux Process ID.
