That's all doable in Rspamd indeed: it has its own resolver library and
it uses persistent processes which also allows caching if needed (and it
uses quite powerful LFU algorithm:
http://antirez.com/news/109).
However, the current integration between Rspamd and Exim is not very
good so far (legacy proto which I have to support in Rspamd just for
Exim, absence of interaction on before-data stages and so on). Perhaps,
it is a topic of some separate discussion at some point...
