Set this variable to t if you want to use blacklists when
splitting incoming mail. Messages whose senders are in the blacklist
will be sent to the spam-split-group. This is an explicit
filter, meaning that it acts only on mail senders declared to
be spammers.
Set this variable to t if you want to use whitelists when
splitting incoming mail. Messages whose senders are not in the
whitelist will be sent to the next spam-split rule. This is an
explicit filter, meaning that unless someone is in the whitelist, their
messages are not assumed to be spam or ham.
Set this variable to t if you want to use whitelists as an
implicit filter, meaning that every message will be considered spam
unless the sender is in the whitelist. Use with care.
Add this symbol to a group’s spam-process parameter by
customizing the group parameters or the
gnus-spam-process-newsgroups variable. When this symbol is
added to a group’s spam-process parameter, the senders of
spam-marked articles will be added to the blacklist.
WARNING
Instead of the obsolete
gnus-group-spam-exit-processor-blacklist, it is recommended
that you use (spam spam-use-blacklist). Everything will work
the same way, we promise.
Add this symbol to a group’s spam-process parameter by
customizing the group parameters or the
gnus-spam-process-newsgroups variable. When this symbol is
added to a group’s spam-process parameter, the senders of
ham-marked articles in ham groups will be added to the
whitelist.
WARNING
Instead of the obsolete
gnus-group-ham-exit-processor-whitelist, it is recommended
that you use (ham spam-use-whitelist). Everything will work
the same way, we promise.
Blacklists are lists of regular expressions matching addresses you consider to be spam senders. For instance, to block mail from any sender at ‘vmadmin.com’, you can put ‘vmadmin.com’ in your blacklist. You start out with an empty blacklist. Blacklist entries use the Emacs regular expression syntax.
Conversely, whitelists tell Gnus what addresses are considered legitimate. All messages from whitelisted addresses are considered non-spam. Also see BBDB Whitelists. Whitelist entries use the Emacs regular expression syntax.
The blacklist and whitelist file locations can be customized with the
spam-directory variable (~/News/spam by default), or
the spam-whitelist and spam-blacklist variables
directly. The whitelist and blacklist files will by default be in the
spam-directory directory, named whitelist and
blacklist respectively.
