9.17.6.5 Blackholes
...................
-- Variable: spam-use-blackholes
This option is disabled by default. You can let Gnus consult the
blackhole-type distributed spam processing systems (DCC, for
instance) when you set this option. The variable
‘spam-blackhole-servers’ holds the list of blackhole servers Gnus
will consult. The current list is fairly comprehensive, but make
sure to let us know if it contains outdated servers.
The blackhole check uses the ‘dig.el’ package, but you can tell
‘spam.el’ to use ‘dns.el’ instead for better performance if you set
‘spam-use-dig’ to ‘nil’. It is not recommended at this time to set
‘spam-use-dig’ to ‘nil’ despite the possible performance
improvements, because some users may be unable to use it, but you
can try it and see if it works for you.
-- Variable: spam-blackhole-servers
The list of servers to consult for blackhole checks.
-- Variable: spam-blackhole-good-server-regex
A regular expression for IPs that should not be checked against the
blackhole server list. When set to ‘nil’, it has no effect.
-- Variable: spam-use-dig
Use the ‘dig.el’ package instead of the ‘dns.el’ package. The
default setting of ‘t’ is recommended.
Blackhole checks are done only on incoming mail. There is no spam or
ham processor for blackholes.
