Use the page to configure lists that define trusted and known bad hosts and
senders, and list of Whitelisted URLs.
- Messages from Allowed List bypass anti-spam
filtering.
- Messages from Blocked List are blocked without being
scanned for spam.
- URLs in Whitelisted URLs will not be rewritten if ToC
Policy is configured to skip those URLs.
Reducing the volume of messages scanned by the
Email Appliance can significantly improve system
performance.
Note Message relays known to be spam senders are included in lists used by
the IP Reputation Filtering feature, which can be configured
on the Policy: Filtering Options page. This page provides the
ability to allow or block senders based on sender reputation data compiled by
SophosLabs. It is important to ensure that a host never appears simultaneously in
the Trusted relay list and the Allowed
Hosts list.
