mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel)
Otherwise the global event handlers accumulate, one added each time
logging is reoladed, and each invocation of the signal or event triggers
one dump of each created ringbuffer.
This module lets you block connections to remote servers at the s2s
level.
``` {.lua}
modules_enabled = {
-- other modules --
"s2s_blacklist",
}
s2s_blacklist = {
"proxy.eu.jabber.org",
}
