Agent Commands Gnus Unplugged Outgoing Messages
nnagent
doesn't handle expiry. Instead, there's a special
gnus-agent-expire
command that will expire all read articles that
are older than gnus-agent-expire-days
days. It can be run
whenever you feel that you're running out of space. It's not
particularly fast or efficient, and it's not a particularly good idea to
interrupt it (with C-g or anything else) once you've started it.
if gnus-agent-expire-all
is non-nil
, this command will
expire all articles---unread, read, ticked and dormant. If nil
(which is the default), only read articles are eligible for expiry, and
unread, ticked and dormant articles will be kept indefinitely.
