[Rspamd-Users] multimap or composites?

[Vu Ngoc VU]

Hello,
I'm kinda new to rspamd and would like to write some combined rules.
E.g. : if the client is from private network (RFC1918) or friendly networks (our corporate group) or partners networks, I want to disable some checks like RBLs.

Looks like both multimap module and composites (is this directly in core rspamd?) allow to combine symbols with conditionals.

So, could someone clarify me the differences between them please?

Regards,
