I set up the rules and finally found that conditional maps is not
working under prefilter mode.
rspamd will pickup the rule randomly.
I don't know if this is a feature or bug?
is conditional maps supposed to work under perfileter mode?
I shrink my rules as below:

 LOCAL_BL_FROM { type = "from"; map =
"/etc/rspamd/local.d/bl_from.map"; description = "Local from
blacklist"; prefilter = true; action = reject; require_symbols =
 "!LOCAL_WL_IP";}
LOCAL_WL_IP { type = "ip"; map = "/etc/rspamd/local.d/wl_ip.map";
description = "Local ip whitelist"; prefilter = true; action =
accept;}

"bl_from.map" content => me at example.com
"wl_ip.map" content => 127.0.0.0/8

my environment is RHEL8 with official
https://rspamd.com/rpm-stable/centos-8/x86_64/rspamd-3.1-1.x86_64.rpm
I try to send mail from webmail to myself (eg: from me at example.com to
me at example.com).

"systemctl restart rspamd" and then try to send webmail.

sometimes the blacklist wins, sometime the whitelist wins. it seems
random. the winner will last until next "systemctl restart rspamd" to
select the new winner.
