Managing End User Lists

Whitelists are used to allow trusted email addresses and hosts to bypass normal spam filtering, which ensures that messages from the listed sources are delivered. Whitelists can be maintained by individual users, enabling personalized processing. End users can be granted the ability to manage their own whitelists through the End User Web Interface (EUWI) or, if access is not granted, administrators can maintain end users' personal whitelists.

Blacklists are used to disallow problem email addresses and hosts (for example, those known to be senders of viruses or spam) before normal spam filtering, which ensures that messages from the listed sources will never be delivered. Blacklists can be maintained by individual users, enabling personalized processing. End users can be granted the ability to manage their own blacklists through the End User Web Interface (EUWI) or, if access is not granted, administrators can maintain end users' personal blacklists.
