[Rspamd-Users] Subscribing to blocklist services for use with Rspamd

[Jason White]

I've recently been working to improve my mail server configuration, and 
I noticed the availability of subscription-based blocklist services 
from, at least, Abusix and Spamhaus. Of course, there may be others.

I suspect my query rate would be sufficiently low to qualify for free 
access under their licensing policies, if I'm reading correctly. I would 
welcome any comments on such services, including their effectiveness in 
reducing spam delivery, Rspamd integration, and whatever else I should 
consider. Which of the available services, if any, should I subscribe 
to, for a small Postfix/Rspamd/Dovecot configuration?
