As for we, whta we finally do is changing this rule:
racl greylist not auth /.*/ default
for this one, that in fact is our default policy:
racl greylist not auth /.*/ delay 10m autowhite 32d
Besides, we add this final rule to our ruleset, for auth users not to be greylisted when
they are not ratelimited:
racl whitelist default
Thanks again
