If 'bouncer' is enabled and you are already logged in and using a nick, a
second client of yours that authenticates with SASL and requests the same nick
is allowed to attach to the nick as well (this is comparable to the behavior
of IRC "bouncers" like ZNC). Your options are 'on' (allow this behavior),
'off' (disallow it), and 'default' (use the server default value).
$bAUTOREPLAY-LINES$b
'autoreplay-lines' controls the number of lines of channel history that will
be replayed to you automatically when joining a channel. Your options are any
positive number, 0 to disable the feature, and 'default' to use the server
default.
$bAUTOREPLAY-JOINS$b
'autoreplay-joins' controls whether autoreplayed channel history will include
lines for join and part. This provides more information about the context of
messages, but may be spammy. Your options are 'on' and 'off'.
