gnus: Blacklists and Whitelists
9.17.6.1 Blacklists and Whitelists
..................................
-- Variable: spam-use-blacklist
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.
-- Variable: spam-use-whitelist
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.
-- Variable: spam-use-whitelist-exclusive
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.
-- Variable: gnus-group-spam-exit-processor-blacklist
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.
-- Variable: gnus-group-ham-exit-processor-whitelist
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.
