To detect spam when visiting a group, set the group’s
spam-autodetect
and spam-autodetect-methods
group
parameters. These are accessible with G c or G p, as
usual (see Group Parameters).
You should set the spam-use-*
variables for whatever spam back
ends you intend to use. The reason is that when loading
spam.el, some conditional loading is done depending on what
spam-use-xyz
variables you have set.
By default, only unseen articles are processed for spam. You can
force Gnus to recheck all messages in the group by setting the
variable spam-autodetect-recheck-messages
to t
.
If you use the spam-autodetect
method of checking for spam, you
can specify different spam detection methods for different groups.
For instance, the ‘ding’ group may have spam-use-BBDB
as
the autodetection method, while the ‘suspect’ group may have the
spam-use-blacklist
and spam-use-bogofilter
methods
enabled. Unlike with spam-split
, you don’t have any control
over the sequence of checks, but this is probably unimportant.
