To manually blacklist, use blacklist_from
to add an address to your blacklist.
If the sender is at all well known (such as a mailing list), you should use {{ Wiki Markup whitelist_from_rcvd
}} instead so that a spammer can't forge their mail to look like it's from the whitelisted address. More info on {{whitelist_from
}}, {{whitelist_from_rcvd
}}, and {{blacklist_from
}} is on the \[http://www.spamassassin.org/doc/Mail_SpamAssassin_Conf.html web\] or can be accessed from your local man pages by typing {{perldoc
Mail::SpamAssassin::Conf
}}.
Some good, free web-based tools are available to put a friendly user interface on whitelists (and blacklists) and allow users to edit their own. See WebUserInterfaces.
