Using blacklists to block senders

To help filter out unwanted email, you can use blacklists to specify hosts and domains that are sources of unwanted email.

When blacklist filters are enabled, any message from a host or domain on the blacklist is tagged. Although you cannot see the tag, your mail application recognizes it and you can create a mail rule to act on messages that have a blacklist tag. For example, you could create a rule that sends all blacklist tagged messages to a folder called SPAM:

WHEN Blacklist tag contains SpamCop THEN move to folder SPAM

In addition to blacklists, the server also tags messages with whitelist tags. A whitelist is a list of exceptions to hosts and domains on a blacklist. To take advantage of the server's whitelist, you can create a mail rule to act on messages that have a whitelist tag.

If blacklist and whitelist filters are enabled on the server, your server's administrator can supply the names on the lists. You can also find this information in the Domino® directory. To view the lists, open the Domino® directory (Names.nsf) on your home mail server, click Configurations under Configuration > Servers, open the server Configurations document, and then click Router/SMTP > Restrictions and Controls > SMTP Inbound Controls. If enabled, the lists display in the DNS Blacklist Filters and DNS Whitelist Filters fields.
